Item 5. Other Events.

         On November 20, 2000, Old Kent Financial Corporation and Fifth Third
entered into an Agreement and Plan of Merger, pursuant to which Old Kent will be
merged with and into Fifth Third.

         As a result of the merger, each issued and outstanding share of Old
Kent common stock (excluding treasury and certain other shares), together with
the preferred stock purchase rights attached thereto, will be converted into
0.74 of a share of Fifth Third common stock. Cash will be paid for any
fractional share of Fifth Third common stock to which any holder of Old Kent
common stock would be entitled pursuant to the merger in lieu of such fractional
share. This exchange ratio is subject to change if, prior to the effective time
of the merger the outstanding shares of Fifth Third common stock or Old Kent
common stock shall have been increased, decreased, changed into or exchanged for
a different number or kind of shares or securities as a result of a
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, or other similar change in capitalization. In this case, an
appropriate and proportionate adjustment shall be made to the exchange ratio.

         Each share of Old Kent series D perpetual preferred stock issued and
outstanding immediately prior to the effective time of the merger shall be
converted into one share of perpetual preferred stock of Fifth Third designated
as Fifth Third series D perpetual preferred stock. The terms of the Fifth Third
series D perpetual preferred stock shall be substantially identical to the
terms of the Old Kent series D perpetual preferred stock, except for such
changes as may be required to give effect to the adjustment required by Section
D.5.3.E. of the certificate of designations, preferences and rights relating
thereto in respect of the merger. Each share of Old Kent series E perpetual
preferred stock issued and outstanding immediately prior to the effective time
of the merger shall be converted into one share of perpetual preferred stock of
Fifth Third designated as Fifth Third series E perpetual preferred stock. The
terms of the Fifth Third series E perpetual preferred stock shall be
substantially identical to the terms of the Old Kent series E perpetual
preferred stock.

         Consummation of the merger will result in the Old Kent common stock
ceasing to be listed on the New York Stock Exchange and the termination of the
registration of such securities pursuant to the Securities Exchange Act of 1934.

         The merger is expected to qualify as a reorganization under the
provisions of Section 368 of the Internal Revenue Code and to be accounted for
as a pooling-of-interests. The merger is subject to approval by the shareholders
of Old Kent, approval by the shareholders of Fifth Third, receipt of certain
regulatory approvals and other customary conditions set forth in the Agreement
and
<PAGE>   3
Plan of Merger. The Agreement and Plan of Merger is included as Exhibit 2.1
hereto and is hereby incorporated herein by reference.

         As a condition and inducement to Fifth Third's entering into the
Agreement and Plan of Merger, Old Kent entered into a Stock Option Agreement
with Fifth Third. Pursuant to the Stock Option Agreement, Old Kent has granted
to Fifth Third an option to purchase up to 19.9% of Old Kent's outstanding
common stock at a price of $25.00 per share, exercisable only upon the
occurrence of certain events. Both the number of shares subject to the option
and the exercise price therefor are subject to adjustment as provided in the
Stock Option Agreement. The Stock Option Agreement is included as Exhibit 4.1
hereto and is hereby incorporated herein by reference.

         Pursuant to the Agreement and Plan of Merger, upon consummation of the
merger, the articles of incorporation of Fifth Third shall be the articles of
incorporation of the surviving corporation, and the code of regulations of Fifth
Third shall be the code of regulations of the surviving corporation, until each
is amended in accordance with law. Additionally, in the Agreement and Plan of
Merger, Fifth Third has agreed: (1) to take all steps reasonably required to
appoint three Directors of Old Kent as Directors of Fifth Third, and (2) to
extend offers to all individuals who are members of the Board of Directors of
Old Kent immediately prior to the effective time of the merger to become members
of the Board of Directors of Fifth Third's principal bank located in Michigan
(or any successor thereto) immediately after the effective time of the merger.

         The Agreement and Plan of Merger may be terminated by either Fifth
Third or Old Kent if the merger has not been consummated by November 20, 2001,
unless the failure of the consummation to occur by such date shall be due to the
failure of the party seeking to terminate the Agreement and Plan of Merger to
perform or observe the covenants and agreements of such party set forth therein.

         The preceding summary of certain provisions of the Agreement and Plan
of Merger and the Stock Option Agreement, copies of which are filed as exhibits
hereto, is not intended to be complete and is qualified in its entirety by
reference to the full text of such agreements.

                      FORWARD-LOOKING STATEMENT DISCLOSURE

         This document contains or may contain forward- looking statements about
Fifth Third Bancorp, Old Kent Financial Corporation and the combined company
which we believe are within the meaning of the Private Securities Litigation
Reform Act of 1995. These forward- looking statements are made in connection to
the financial condition, results of operations, plans, objectives, future
performance and business of Fifth Third and/or the combined company. These
forward- looking statements involve certain risks and uncertainties. There are a
number of important factors that could cause future results to differ materially
from historical performance and these forward- looking statements. Factors that
might cause such a difference include, but are not limited to: (1) competitive
pressures among depository institutions increase significantly; (2) changes in
the interest rate environment reduce interest margins; (3) prepayment speeds,
loan sale volumes, charge-offs and loan loss provisions; (4) general economic
conditions, either
<PAGE>   4
national or in the states in which Fifth Third and Old Kent do business, are
less favorable than expected; (5) legislative or regulatory changes adversely
affect the businesses in which Fifth Third and Old Kent are engaged; and (6)
changes in the securities markets. Further information on other factors which
could effect the financial results of Fifth Third after the merger are included
in Fifth Third's and Old Kent's filings with the SEC. These documents are
available free of charge at the SEC's website at http://www.sec.gov and/or from
Fifth Third or Old Kent.

                  AGREEMENT AND PLAN OF MERGER, dated as of November 20, 2000
(including all schedules and exhibits attached hereto, this "Agreement"), by and
between OLD KENT FINANCIAL CORPORATION, a Michigan corporation ("Old Kent"), and
FIFTH THIRD BANCORP, an Ohio corporation ("Fifth Third").

                              W I T N E S S E T H:

                  WHEREAS, the Boards of Directors of Old Kent and Fifth Third
have determined that it is in the best interests of their respective companies
and their stockholders to consummate the strategic business combination
transaction provided for herein in which Old Kent will, subject to the terms and
conditions set forth herein, merge with and into Fifth Third (the "Merger"), so
that Fifth Third is the surviving corporation in the Merger (sometimes referred
to in such capacity as the "Surviving Corporation"); and

                  WHEREAS, as a condition to the execution of this Agreement,
and simultaneously with the execution hereof, Old Kent and Fifth Third are
entering into a stock option agreement (the "Old Kent Option Agreement") in the
form attached hereto as Exhibit A; and

                  WHEREAS, for Federal Income Tax purposes, it is intended that
the Merger shall qualify as a reorganization under the provisions of Section 368
of the Internal Revenue Code of 1986, as amended (the "Code"), and this
Agreement is intended to be and is adopted as a plan of reorganization for
purposes of Sections 354, 361 and 368 of the Code; and

                  WHEREAS, the parties desire to make certain representations,
warranties and agreements in connection with the Merger and also to prescribe
certain conditions to the Merger.

                  NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound hereby, the parties agree as
follows:

                                       1
<PAGE>   9
                                    ARTICLE I


                                   THE MERGER

                  1.1 The Merger. (a) Subject to the terms and conditions of
this Agreement, in accordance with the Michigan Business Corporation Act (the
"MBCA") and the Ohio General Corporation Law (the "OGCL"), at the Effective
Time, Old Kent shall merge with and into Fifth Third. Fifth Third shall be the
Surviving Corporation in the Merger, and shall continue its corporate existence
under the laws of the State of Ohio.

                  (b) Fifth Third may at any time change the method of effecting
the combination with Old Kent (including by providing for the merger of a wholly
owned subsidiary of Fifth Third with and into Old Kent) if and to the extent
Fifth Third deems such change to be desirable; provided, however, that no such
change shall (i) alter or change the amount or kind of consideration to be
issued to holders of the Old Kent Common Stock as provided for in this Agreement
(the "Merger Consideration"), (ii) adversely affect the Tax treatment of the
holders of Old Kent Common Stock as a result of receiving the Merger
Consideration or (iii) materially impede or delay consummation of the
transactions contemplated by this Agreement. Old Kent shall, if requested by
Fifth Third, enter into one or more amendments to this Agreement prior to the
Effective Time in order to effect any such change.

                  1.2 Effective Time. The Merger shall become effective as set
forth in the certificate of merger (the "Ohio Certificate of Merger") that shall
be filed with the Secretary of State of the State of Ohio and the certificate of
merger (the "Michigan Certificate of Merger") that shall be filed with the
appropriate office of the State of Michigan on the Closing Date (together with
the Ohio Certificate of Merger, the "Certificates of Merger"). The term
"Effective Time" shall be the date and time when the Merger becomes effective as
set forth in the Certificates of Merger which shall not be later than the
Closing Date.

                  1.3 Effects of the Merger. At and after the Effective Time,
the Merger shall have the effects set forth in Section 1701.82 of the OGCL and
Section 724 of the MBCA.

                  1.4 Conversion of Old Kent Capital Stock. At the Effective
Time, by virtue of the Merger and without any action on the part of Fifth Third,
Old Kent or the holder of any of the following securities:

                  (a) Subject to Section 2.2(e), each share of the common stock
(the "Old Kent Common Stock"), par value $1.00 per share, of Old Kent issued and
outstanding immediately prior to the Effective Time (together with the preferred
stock purchase rights ("Old Kent Stockholder Rights") attached thereto issued
pursuant to that certain Rights Agreement, between Old Kent and Old Kent Bank
dated as of January 20, 1997, as amended as of December 30, 1998 (the "Old Kent
Rights Agreement"), except for shares of Old Kent Common Stock owned by Old Kent
as treasury stock or owned,

                                       2
<PAGE>   10
directly or indirectly, by Old Kent or Fifth Third (other than shares of Old
Kent Common Stock held, directly or indirectly, in trust accounts, managed
accounts and the like, or otherwise held in a fiduciary capacity, that are
beneficially owned by third parties (any such shares of Old Kent Common Stock
which are similarly held, whether held directly or indirectly by Old Kent or
Fifth Third, as the case may be, being referred to herein as "Trust Account
Shares") and other than any shares of Old Kent Common Stock held by Old Kent or
Fifth Third in respect of a debt previously contracted (any such shares of Old
Kent Common Stock which are similarly held, whether held directly or indirectly
by Old Kent or Fifth Third, being referred to herein as "DPC Shares")), shall be
converted into the right to receive 0.74 of a share (the "Exchange Ratio") of
the common stock, without par value, of Fifth Third (the "Fifth Third Common
Stock").

                  (b) All of the shares of Old Kent Common Stock converted into
the right to receive Fifth Third Common Stock pursuant to this Article I shall
no longer be outstanding and shall automatically be cancelled and shall cease to
exist as of the Effective Time, and each certificate previously representing any
such shares of Old Kent Common Stock (each a "Certificate") shall thereafter
represent only the right to receive (i) a certificate representing the number of
whole shares of Fifth Third Common Stock and (ii) cash in lieu of fractional
shares into which the shares of Old Kent Common Stock represented by such
Certificate have been converted pursuant to this Section 1.4 and Section 2.2(e).
Certificates previously representing shares of Old Kent Common Stock shall be
exchanged for certificates representing whole shares of Fifth Third Common Stock
and cash in lieu of fractional shares issued in consideration therefor upon the
surrender of such Certificates in accordance with Section 2.2, without any
interest thereon. If, prior to the Effective Time, the outstanding shares of
Fifth Third Common Stock or Old Kent Common Stock shall have been increased,
decreased, changed into or exchanged for a different number or kind of shares or
securities as a result of a reorganization, recapitalization, reclassification,
stock dividend, stock split, reverse stock split, or other similar change in
capitalization, an appropriate and proportionate adjustment shall be made to the
Exchange Ratio.

                  (c) Notwithstanding anything in the Agreement to the contrary,
at the Effective Time, all shares of Old Kent Common Stock that are owned,
directly or indirectly, by Old Kent or Fifth Third (other than Trust Account
Shares and DPC Shares) shall be cancelled and shall cease to exist and no stock
of Fifth Third or other consideration shall be delivered in exchange therefor.

                  (d) Each share of Old Kent Series D Perpetual Preferred Stock,
issued and outstanding immediately prior to the Effective Time shall be
converted, automatically and without the requirement of any exchange of any
certificate representing such stock, into one share of perpetual preferred stock
of Fifth Third designated as Fifth Third Series D Perpetual Preferred Stock. The
terms of the Fifth Third Series D Perpetual Preferred Stock shall be
substantially identical to the terms of the Old Kent Series D Perpetual
Preferred Stock, except for such changes as may be required to give effect to
the adjustment required by Section D.5.3.E. of the certificate of designations,
preferences and rights relating thereto in respect of the Merger.

<PAGE>   11
                  (e) Each share of Old Kent Series E Perpetual Preferred Stock
(together with the Old Kent Series D Perpetual Preferred Stock, the "Old Kent
Perpetual Preferred Stock"), issued and outstanding immediately prior to the
Effective Time shall be converted, automatically and without the requirement of
any exchange of any certificate representing such stock, into one share of
perpetual preferred stock of Fifth Third designated as Fifth Third Series E
Perpetual Preferred Stock (together with the Fifth Third Series D Perpetual
Preferred Stock, the "Fifth Third New Preferred Stock"). The terms of the Fifth
Third Series E Perpetual Preferred Stock shall be substantially identical to the
terms of the Old Kent Series E Perpetual Preferred Stock.

                  (f) All of the shares of Old Kent Perpetual Preferred Stock
converted into Fifth Third New Preferred Stock pursuant to this Article I shall
no longer be outstanding and shall automatically be cancelled and shall cease to
exist as of the Effective Time, and each certificate previously representing any
such shares of Old Kent Perpetual Preferred Stock shall as of the Effective Time
be deemed to represent as of the Effective Time the number of shares of
corresponding Fifth Third New Preferred Stock into which the shares of Old Kent
Perpetual Preferred Stock represented by such preferred stock certificate have
been converted pursuant to this Section 1.4.

                  1.5 Fifth Third Capital Stock. At and after the Effective
Time, each share of Fifth Third Common Stock and each share of preferred stock,
without par value, of Fifth Third (the "Fifth Third Preferred Stock," and
together with the Fifth Third Common Stock, the "Fifth Third Capital Stock")
issued and outstanding immediately prior to the Effective Time shall remain
issued and outstanding and shall not be affected by the Merger.

                  1.6 Options. (a) At the Effective Time, each option granted by
Old Kent to purchase shares of Old Kent Common Stock which is outstanding and
unexercised immediately prior thereto shall cease to represent a right to
acquire shares of Old Kent Common Stock and shall be converted automatically
into an option to purchase shares of Fifth Third Common Stock in an amount and
at an exercise price determined as provided below (and otherwise subject to the
terms of, as the case may be, the Old Kent Executive Stock Option Plan of 1986,
the Old Kent Restricted Stock Plan of 1987, the Old Kent Stock Option Incentive

and the Directors' Deferred Compensation Plan in each case as amended through
the date hereof (collectively, the "Old Kent Stock Plans"), and the agreements
evidencing grants thereunder):

                  (i) The number of shares of Fifth Third Common Stock to be
subject to the new option shall be equal to the product of the number of shares
of Old Kent Common Stock subject to the original option and the Exchange Ratio,
provided that any fractional shares of Fifth Third Common Stock resulting from
such multiplication shall be rounded to the nearest whole share; and

                  (ii) The exercise price per share of Fifth Third Common Stock
under the new option shall be equal to the exercise price per share of Old Kent
Common Stock under the original option divided by the Exchange Ratio, provided
that such exercise price shall be rounded to the nearest whole cent.

                  (b) The adjustment provided herein with respect to any options
which are "incentive stock options" (as defined in Section 422 of the Code)
shall be and is intended to be effected in a manner which is consistent with
Section 424(a) of the Code. The duration and other terms of the new option shall
be the same as the original option except that all references to Old Kent shall
be deemed to be references to Fifth Third.

                  (c) Fifth Third shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Fifth Third Common Stock
for delivery upon exercise of Old Kent Stock Options, as adjusted in accordance
with this Section 1.6. As soon as practicable after the Effective Time, Fifth
Third shall file a registration statement on Form S-8 (or any successor or other
appropriate forms), with respect to the shares of Fifth Third Common Stock
subject to such options and shall use its reasonable best efforts to maintain
the effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding.

Time, the Fifth Third Articles shall be the articles of incorporation of the
Surviving Corporation until thereafter amended in accordance with applicable
law.

law.

                  1.9 Tax and Accounting Consequences. It is intended that the
Merger shall constitute a "reorganization" within the meaning of Section 368(a)
of the Code, that this Agreement shall constitute a "plan of reorganization" for
the purposes of Sections 354, 361 and 368 of the Code and that the Merger shall
be accounted for as a "pooling of interests" under generally accepted accounting
principles ("GAAP").

                               EXCHANGE OF SHARES

                  2.1 Fifth Third to Make Shares Available. At or prior to the
Effective Time, Fifth Third shall deposit, or shall cause to be deposited, with
a bank or trust company Subsidiary of Fifth Third, or another bank or trust
company reasonably acceptable to each of Old Kent and Fifth Third (the "Exchange
Agent"), for the benefit of the holders of Certificates, for exchange in
accordance with this Article II, certificates representing the shares of Fifth
Third Common Stock, and cash in lieu of any fractional shares (such cash and
certificates for shares of Fifth Third Common Stock, together with any dividends
or distributions with respect thereto, being hereinafter referred to as the
"Exchange Fund"), to be issued pursuant to Section 1.4 and paid pursuant to
Section 2.2(a) in exchange for outstanding shares of Old Kent Common Stock.

                  2.2 Exchange of Shares. (a) As soon as practicable after the
Effective Time, but in no event more than 10 days after the later of the Closing
Date or the date the Exchange Agent shall have received from Old Kent a
substantially complete list of the final shareholders of Old Kent as of the
Effective Time, the Exchange Agent shall mail to each holder of record of one or
more Certificates a letter of transmittal in customary form as reasonably agreed
to by the parties (which shall specify, among other things, that delivery shall
be effected, and risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates to the Exchange Agent) and instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing the shares of Fifth Third Common Stock and any cash in lieu of
fractional shares into which the shares of Old Kent Common Stock represented by
such Certificate or Certificates shall have been converted pursuant to this
Agreement. Upon proper surrender of a Certificate or Certificates for exchange
and cancellation to the Exchange Agent, together with such properly completed
letter of transmittal, duly executed, the holder of such Certificate or
Certificates shall be entitled to receive in exchange therefor, as applicable,
(i) a certificate representing that number of whole shares of Fifth Third Common
Stock to which such holder of Old Kent Common Stock shall have become entitled
pursuant to the provisions of Article I, (ii) a check representing the amount of
any cash in lieu of fractional shares which such holder has the right to receive
in respect of the Certificate or Certificates surrendered pursuant to the
provisions of this Article II, and (iii) a check representing the amount of any
dividends or distributions then payable pursuant to Section 2.2(b)(i) and the
Certificate or Certificates so surrendered shall forthwith be cancelled. No
interest will be paid or accrued on any cash in lieu of fractional shares or on
any unpaid dividends and distributions payable to holders of Certificates.

                  (b) No dividends or other distributions declared with respect
to Fifth Third Common Stock shall be paid to the holder of any unsurrendered
Certificate until the holder thereof shall surrender such Certificate in
accordance with this Article II. After the surrender of a Certificate in
accordance with this Article II, the record holder thereof shall be entitled to
receive (i) the amount of dividends or other distributions

                                       6
<PAGE>   14
with a record date after the Effective Time theretofore paid, without any
interest thereon, which theretofore had become payable and (ii), at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and a payment date
subsequent to surrender, with respect to shares of Fifth Third Common Stock
represented by such Certificate.

                  (c) If any certificate representing shares of Fifth Third
Common Stock is to be issued in a name other than that in which the Certificate
or Certificates surrendered in exchange therefor is or are registered, it shall
be a condition of the issuance thereof that the Certificate or Certificates so
surrendered shall be properly endorsed (or accompanied by an appropriate
instrument of transfer) and otherwise in proper form for transfer, and that the
person requesting such exchange shall pay to the Exchange Agent in advance any
transfer or other Taxes required by reason of the issuance of a certificate
representing shares of Fifth Third Common Stock in any name other than that of
the registered holder of the Certificate or Certificates surrendered, or
required for any other reason, or shall establish to the satisfaction of the
Exchange Agent that such Tax has been paid or is not payable.

                  (d) After the Effective Time, there shall be no transfers on
the stock transfer books of Old Kent of the shares of Old Kent Capital Stock
that were issued and outstanding immediately prior to the Effective Time other
than to settle transfers of Old Kent Common Stock that occurred prior to the
Effective Time and otherwise as necessary to prepare a list of the final
shareholders of Old Kent. If, after the Effective Time, Certificates
representing such shares are presented for transfer to the Exchange Agent, they
shall be cancelled and exchanged for certificates representing shares of Fifth
Third Common Stock as provided in this Article II.

                  (e) Notwithstanding anything to the contrary contained herein,
no certificates or scrip representing fractional shares of Fifth Third Common
Stock shall be issued upon the surrender for exchange of Certificates, no
dividend or distribution with respect to Fifth Third Common Stock shall be
payable on or with respect to any fractional share, and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a stockholder of Fifth Third. In lieu of the issuance of any such fractional
share, Fifth Third shall pay to each former stockholder of Old Kent who
otherwise would be entitled to receive such fractional share an amount in cash
determined by multiplying (i) the average of the closing-sale prices of Fifth
Third Common Stock on the NASDAQ National Market (the "NASDAQ") as reported by
The Wall Street Journal for the five trading days immediately preceding the
Closing Date by (ii) the fraction of a share (rounded to the nearest thousandth
when expressed in decimal form) of Fifth Third Common Stock which such holder
would otherwise be entitled to receive pursuant to Section 1.4.

                  (f) Any portion of the Exchange Fund that remains unclaimed by
the stockholders of Old Kent for 12 months after the Effective Time shall be
paid to Fifth Third. Any former stockholders of Old Kent who have not
theretofore complied with this Article II shall thereafter look only to Fifth
Third for payment of the shares of Fifth

                                       7
<PAGE>   15
Third Common Stock, cash in lieu of any fractional shares and any unpaid
dividends and distributions on the Fifth Third Common Stock deliverable in
respect of each share of Old Kent Common Stock, as the case may be, such
stockholder holds as determined pursuant to this Agreement, in each case,
without any interest thereon. Notwithstanding the foregoing, none of Fifth
Third, Old Kent, the Exchange Agent or any other person shall be liable to any
former holder of shares of Old Kent Common Stock for any amount delivered in
good faith to a public official pursuant to applicable abandoned property,
escheat or similar laws.

                  (g) In the event any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if reasonably
required by Fifth Third, the posting by such person of a bond in such amount as
Fifth Third may determine is reasonably necessary as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate the shares
of Fifth Third Common Stock and any cash in lieu of fractional shares
deliverable in respect thereof pursuant to this Agreement.

                                   ARTICLE III


                   REPRESENTATIONS AND WARRANTIES OF OLD KENT

                  Except as disclosed in (i) the Old Kent disclosure schedule
delivered to Fifth Third prior to the execution of this Agreement (the "Old Kent
Disclosure Schedule") or (ii) the Old Kent Reports filed prior to the date
hereof, Old Kent hereby represents and warrants to Fifth Third as follows:

                3.1 Corporate Organization. (a) Old Kent is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Michigan. Old Kent has the corporate power and authority to own or lease all of
its properties and assets and to carry on its business as it is now being
conducted, and is duly licensed or qualified to do business in each jurisdiction
in which the nature of the business conducted by it or the character or location
of the properties and assets owned or leased by it makes such licensing or
qualification necessary, except where the failure to be so licensed or qualified
would not, either individually or in the aggregate, have a Material Adverse
Effect on Old Kent. As used in this Agreement, the term "Material Adverse
Effect" means, with respect to Fifth Third, Old Kent or the Surviving
Corporation, as the case may be, a material adverse effect on (i) the business,
results of operations or financial condition of such party and its Subsidiaries
taken as a whole or (ii) the ability of such party to timely consummate the
transactions contemplated hereby; provided, however, that Material Adverse
Effect shall not be deemed to include effects to the extent resulting from (a)
changes in generally accepted accounting principles or regulatory accounting
requirements applicable to banks or savings associations and their holding
companies generally, (b) actions or omissions of Fifth Third or Old Kent taken
with the prior written consent of the other in contemplation of the transactions
contemplated hereby and (c) changes in general economic conditions affecting
banks or

                                       8
<PAGE>   16
their holding companies generally.

                  (b) Old Kent is duly registered as a bank holding company
under the Bank Holding Company Act of 1956, as amended (the "BHC Act"). True and
complete copies of the Restated Articles of Incorporation of Old Kent (the "Old
Kent Articles") and the Bylaws of Old Kent (the "Old Kent Bylaws") have
previously been made available by Old Kent to Fifth Third. Old Kent was
certified as a "financial holding company" (an "FHC") within the meaning of
Section 2(p) of the BHC Act, and remains a certified FHC on the date hereof.

                  (c) Each of Old Kent's Subsidiaries (i) is duly organized and
validly existing under the laws of its jurisdiction of organization, (ii) is
duly qualified to do business and in good standing in all jurisdictions (whether
federal, state, local or foreign) where its ownership or leasing of property or
the conduct of its business requires it to be so qualified and in which the
failure to be so qualified would have a Material Adverse Effect on Old Kent and
(iii) has all requisite corporate power and authority to own or lease its
properties and assets and to carry on its business as now conducted. As used in
this Agreement, the word "Subsidiary" when used with respect to any party, means
any bank, corporation, partnership, limited liability company, or other
organization, whether incorporated or unincorporated, which is consolidated with
such party for financial reporting purposes, and the words "Old Kent Subsidiary"
and "Fifth Third Subsidiary" shall mean any direct or indirect Subsidiary of Old
Kent or Fifth Third, respectively.

                  (d) Section 3.1(d) of the Old Kent Disclosure Schedule sets
forth the names of each of the entities in which Old Kent holds, in the
aggregate, at least 5% of the issued and outstanding shares of capital stock or
voting power.

                  3.2 Capitalization. (a) The authorized capital stock of Old

shares were held in treasury, and (ii) 25,000,000 shares of preferred stock,
without par value (the "Old Kent Preferred Stock," and, together with the Old

validly issued and are fully paid, nonassessable and free of preemptive rights,
with no personal liability attaching to the ownership thereof. As of the date of
this Agreement, except as described in this Section 3.2(a) and except pursuant

<PAGE>   17
outstanding subscriptions, options, warrants, calls, commitments or agreements
of any character calling for the purchase or issuance of any shares of Old Kent
Capital Stock or any other equity securities of Old Kent or any securities
representing the right to purchase or otherwise receive any shares of Old Kent
Capital Stock (collectively, including the items contemplated by clauses (i)

Old Kent Disclosure Schedule, 1,000,000 shares of Series C Preferred Stock of
Old Kent, were reserved for issuance in connection with the Old Kent Rights
Agreement and 417,000 shares of Old Kent Common Stock were reserved for issuance
in connection with the conversion of the Old Kent Series D Perpetual Preferred

capital stock or any securities convertible into or exercisable for any shares
of its capital stock, other than as permitted by Section 5.2(b). Old Kent has
previously provided Fifth Third with a list of the aggregate number of options
outstanding under the Old Kent Stock Plans as of September 30, 2000 and the
weighted average exercise price for such options.

                  (b) Old Kent owns, directly or indirectly, all of the issued
and outstanding shares of capital stock or other equity ownership interests of
each of Old Kent's Subsidiaries, free and clear of any material liens, pledges,
charges and security interests and similar encumbrances ("Liens"), and all of
such shares or equity ownership interests are duly authorized and validly issued
and are fully paid, nonassessable and free of preemptive rights, with no
personal liability attaching to the ownership thereof. No Old Kent Subsidiary
has or is bound by any outstanding subscriptions, options, warrants, calls,
commitments or agreements of any character calling for the purchase or issuance
of any shares of capital stock or any other equity security of such Subsidiary
or any securities representing the right to purchase or otherwise receive any
shares of capital stock or any other equity security of such Subsidiary. Section
3.2(b) of the Old Kent Disclosure Schedule sets forth a list of the material
investments of Old Kent in corporations, joint ventures, partnerships, limited
liability companies and other entities other than its Subsidiaries.

                  3.3 Authority; No Violation. (a) Old Kent has full corporate
power and authority to execute and deliver this Agreement and the Old Kent
Option Agreement and to consummate the transactions contemplated hereby and
thereby. The execution and delivery of this Agreement and the Old Kent Option
Agreement and the consummation of the transactions contemplated hereby and
thereby have been duly and validly approved by the Board of Directors of Old
Kent. The Board of Directors of Old Kent has determined that this Agreement and
the transactions contemplated hereby are in the best interests of Old Kent and
its stockholders and has directed that this Agreement and the transactions
contemplated hereby be submitted to Old Kent's

                                       10

except for the approval of this Agreement and the transactions contemplated
hereby by the affirmative vote of the holders of a majority of the outstanding
shares of Old Kent Common Stock voted at such meeting, no other corporate
proceedings on the part of Old Kent are necessary to approve this Agreement or
the Old Kent Option Agreement or to consummate the transactions contemplated
hereby or thereby. This Agreement and the Old Kent Option Agreement have been
duly and validly executed and delivered by Old Kent and (assuming due
authorization, execution and delivery by Fifth Third) constitute valid and
binding obligations of Old Kent, enforceable against Old Kent in accordance with
its terms (except as may be limited by bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting the rights of creditors generally and
the availability of equitable remedies).

                  (b) Neither the execution and delivery of this Agreement or
the Old Kent Option Agreement by Old Kent nor the consummation by Old Kent of
the transactions contemplated hereby or thereby, nor compliance by Old Kent with
any of the terms or provisions hereof or thereof, will (i) violate any provision
of the Old Kent Articles or the Old Kent Bylaws or (ii) assuming that the
consents and approvals referred to in Section 3.4 are duly obtained, (x) violate

or provisions of any note, bond, mortgage, indenture, deed of trust, license,
lease, agreement or other instrument or obligation to which Old Kent or any of
its Subsidiaries is a party, or by which they or any of their respective
properties or assets may be bound or affected, except (in the case of clause (y)
above) for such violations, conflicts, breaches or defaults which, either
individually or in the aggregate, will not have a Material Adverse Effect on Old
Kent.

                  3.4 Consents and Approvals. Except for (i) the filing of
applications and notices, as applicable, with the Board of Governors of the
Federal Reserve System (the "Federal Reserve Board") under the BHC Act and the

                3.5 Reports. Old Kent and each of its Subsidiaries have timely
filed all reports, registrations and statements, together with any amendments
required to be made with respect thereto, that they were required to file since
January 1, 1997 with (i) the Federal Reserve Board, (ii) the Federal Deposit
Insurance Corporation, (iii) any state regulatory authority, (iv) the SEC, (v)
any foreign regulatory authority and (vi) any SRO (collectively, "Regulatory

States, any state, any foreign entity, or any Regulatory Agency, and have paid
all fees and assessments due and payable in connection therewith, except where
the failure to file such report, registration or statement or to pay such fees
and assessments, either individually or in the aggregate, will not have a
Material Adverse Effect on Old Kent. Except for normal examinations conducted by
a Regulatory Agency in the ordinary course of the business of Old Kent and its
Subsidiaries, no Regulatory Agency has initiated or has pending any proceeding
or, to the best knowledge of Old Kent, investigation into the business or
operations of Old Kent or any of its Subsidiaries since January 1, 1997, except
where such proceedings or investigation will not, either individually or in the
aggregate, have a Material Adverse Effect on Old Kent. There (i) is no
unresolved violation, criticism, or exception by any Regulatory Agency with
respect to any report or statement relating to any examinations or inspections
of Old Kent or any of its Subsidiaries and (ii) has been no formal or informal
inquiries by, or disagreements or disputes with, any Regulatory Agency with
respect to the business, operations policies or procedures of Old Kent since
January 1, 1997, which, in the

                                       12
<PAGE>   20
reasonable judgment of Old Kent, will, either individually or in the aggregate,
have a Material Adverse Effect on Old Kent.

                  3.6 Financial Statements. Old Kent has previously made
available to Fifth Third copies of (i) the consolidated balance sheet of Old
Kent and its Subsidiaries as of December 31, for the fiscal years 1998 and 1999,
and the related consolidated statements of income, changes in shareholders'
equity and cash flows for the fiscal years 1997 through 1999, inclusive, as
reported in Old Kent's Annual Report on Form 10-K for the fiscal year ended
December 31, 1999 (the "Old Kent 1999 10-K") filed with the SEC under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), accompanied by
the audit report of Arthur Andersen LLP, independent public accountants with
respect to Old Kent and (ii) the unaudited consolidated balance sheet of Old
Kent and its Subsidiaries as of September 30, 1999 and 2000, and the related
consolidated statements of income, changes in shareholders' equity and cash
flows of the nine month periods then ended, as reported in Old Kent's Quarterly
Report on Form 10-Q for the fiscal period ended September 30, 2000. The December
31, 1999 consolidated balance sheet of Old Kent (including the related notes,
where applicable) fairly presents in all material respects the consolidated
financial position of Old Kent and its Subsidiaries as of the date thereof, and
the other financial statements referred to in this Section 3.6 (including the
related notes, where applicable) fairly present in all material respects the
results of the consolidated operations and changes in stockholders' equity and
consolidated financial position of Old Kent and its Subsidiaries for the
respective fiscal periods or as of the respective dates therein set forth,
subject to normal year-end audit adjustments in amounts consistent with past
experience in the case of unaudited statements; each of such statements
(including the related notes, where applicable) complies in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto; and each of such statements
(including the related notes, where applicable) has been prepared in all
material respects in accordance with GAAP consistently applied during the
periods involved, except, in each case, as indicated in such statements or in
the notes thereto. The books and records of Old Kent and its Subsidiaries have
been, and are being, maintained in all material respects in accordance with GAAP
and any other applicable legal and accounting requirements and reflect only
actual transactions.

                  3.7 Broker's Fees. Neither Old Kent nor any Old Kent
Subsidiary nor any of their respective officers or directors has employed any
broker or finder or incurred any liability for any broker's fees, commissions or

the Merger or related transactions contemplated by this Agreement.

                  3.8 Absence of Certain Changes or Events. (a) Since December

in the aggregate, a Material Adverse Effect on Old Kent.

                                       13
<PAGE>   21
                  (b) Since December 31, 1999 through and including the date
hereof, Old Kent and its Subsidiaries have carried on their respective
businesses in all material respects in the ordinary course.

                  (c) Since December 31, 1999, neither Old Kent nor any of its
Subsidiaries has (i) except for normal increases for employees (other than
officers subject to the reporting requirements of Section 16(a) of the Exchange
Act) made in the ordinary course of business consistent with past practice or as
required by applicable law, increased the wages, salaries, compensation,
pension, or other fringe benefits or perquisites payable to any executive
officer, employee, or director from the amount thereof in effect as of December
31, 1999, granted any severance or termination pay, entered into any contract to
make or grant any severance or termination pay, or paid any bonus other than the
customary year-end bonuses for fiscal 2000 and 1999 in amounts consistent with
past practice, (ii) granted any stock appreciation rights or granted any rights
to acquire any shares of its capital stock to any executive officer, director or
employee other than grants to employees (other than officers subject to the
reporting requirements of Section 16(a) of the Exchange Act) made in the
ordinary course of business consistent with past practice under the Old Kent
Stock Plans and except as permitted by Section 5.2(b)(iii), or (iii) suffered
any strike, work stoppage, slow-down, or other labor disturbance.

                  3.9 Legal Proceedings. (a) Neither Old Kent nor any of its
Subsidiaries is a party to any, and there are no pending or, to the best of Old
Kent's knowledge, threatened, legal, administrative, arbitral or other
proceedings, claims, actions or governmental or regulatory investigations of any
nature against Old Kent or any of its Subsidiaries or challenging the validity
or propriety of the transactions contemplated by this Agreement or the Old Kent
Option Agreement as to which, in any such case, there is a reasonable
probability of an adverse determination and which, if adversely determined,
will, either individually or in the aggregate, have a Material Adverse Effect on
Old Kent.

                  (b) There is no Injunction, judgment, or regulatory
restriction (other than those of general application that apply to similarly
situated bank holding companies or their Subsidiaries) imposed upon Old Kent,
any of its Subsidiaries or the assets of Old Kent or any of its Subsidiaries
that has had, or will have, either individually or in the aggregate, a Material
Adverse Effect on Old Kent or the Surviving Corporation.

                  3.10 Taxes and Tax Returns. (a) Each of Old Kent and its
Subsidiaries has duly filed all federal, state, foreign and local information
returns and Tax returns required to be filed by it on or prior to the date
hereof (all such returns being accurate and complete in all material respects)
and has duly paid or made provision for the payment of all Taxes and other
governmental charges which have been incurred or are due or claimed to be due
from it by federal, state, foreign or local taxing authorities (including,
without limitation, if and to the extent applicable, those due in respect of its
properties, income, business, capital stock, deposits, franchises, licenses,
sales and payrolls) other than (i) Taxes or other government charges which are
not yet delinquent

                                       14
<PAGE>   22
or are being contested in good faith, have not been finally determined and have
been adequately reserved against in accordance with GAAP or (ii) information
returns, Tax returns, Taxes or other governmental charges as to which the
failure to file, pay or make provision for will not have, either individually or
in the aggregate, a Material Adverse Effect on Old Kent. The federal income Tax
returns of Old Kent and its Subsidiaries have been examined by the Internal
Revenue Service (the "IRS") for all years from 1990 to and including 1995 and
any liability with respect thereto has been satisfied or any liability with
respect to deficiencies asserted as a result of such examination is covered by
adequate reserves. There are no material disputes pending, or claims asserted,
for Taxes or assessments upon Old Kent or any of its Subsidiaries for which Old
Kent does not have adequate reserves maintained in accordance with GAAP. Neither
Old Kent nor any of its Subsidiaries is a party to or is bound by any Tax
sharing, allocation or indemnification agreement or arrangement (other than such
an agreement or arrangement exclusively between or among Old Kent and its
Subsidiaries). Within the past five years, neither Old Kent nor any of its
Subsidiaries has been a "distributing corporation" or a "controlled corporation"
in a distribution intended to qualify under Section 355(a) of the Code.

                  (b) As used in this Agreement, the term "Tax" or "Taxes" means
(i) all federal, state, local, and foreign income, excise, gross receipts, gross
income, and valorem, profits, gains, property, capital, sales, transfer, use,
payroll, employment, severance, withholding, duties, intangibles, franchise,
backup withholding, and other taxes, charges, levies or like assessments
together with all penalties and additions to tax and interest thereon and (ii)
any liability for Taxes described in clause (i) under Treasury Regulation
Section 1.1502-6 (or any similar provision of state, local or foreign law).

                  (c) No disallowance of a deduction under Section 162(m) of the
Code for employee remuneration of any amount paid or payable by Old Kent or any
of its Subsidiaries under any contract, plan, program, arrangement or
understanding would be reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Old Kent.

                  3.11 Employees. (a) The Old Kent Disclosure Schedule sets
forth a true and complete list of each material employee or director benefit or
compensation plan, arrangement or agreement, and any material bonus, incentive,
deferred compensation, vacation, stock purchase, stock option, severance,
employment, change of control or fringe benefit plan, program or agreement that
is maintained, or contributed to, presently or at any time within the last four
(4) years (the "Old Kent Benefit Plans") by Old Kent, any of its Subsidiaries or
by any trade or business, whether or not incorporated (a "Old Kent ERISA
Affiliate"), all of which together with Old Kent would be deemed a "single
employer" within the meaning of Section 4001 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"). The term "Benefit Plan" for all
purposes of this Agreement shall include each Predecessor Plan (as herein

policy, practice, arrangement, agreement or system as otherwise described in
Section 3.12(a)

                                       15

type of acquisition (including, without limitation, mergers, stock acquisitions
and asset acquisitions).

                  (b) Old Kent has heretofore made available to Fifth Third true
and complete copies of each of the Old Kent Benefit Plans and certain related

most recent determination letter from the IRS (if applicable) for such Old Kent
Benefit Plan.

                  (c) Except for such noncompliance as would not have, and would
not reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on Old Kent, (i) each of the Old Kent Benefit Plans has been
operated and administered in all material respects in compliance with applicable
laws, including, but not limited to, ERISA and the Code, (ii) each of the Old
Kent Benefit Plans intended to be "qualified" within the meaning of Section 401
(a) of the Code is so qualified, and there are no existing circumstances or any

determined that such Qualified Benefit Plan (as amended by any and all
amendments) satisfies the requirements of Section 401(a) of the Code, as amended
by all the laws referred to in Section 1 of Revenue Procedure 93-39, such
determination letter has not been revoked or threatened to be revoked by the
IRS, and the scope of such determination letter is complete and does not exclude
consideration of any of the requirements or matters referred to in Sections 4.02
through 4.04 of Revenue Procedure 93-39 (iii) with respect to each Old Kent
Benefit Plan that is subject to Title IV of ERISA, the present value (as defined
under Section 3(26) of ERISA) of accumulated benefit obligations under such Old
Kent Benefit Plan, based upon the actuarial assumptions used for funding
purposes in the most recent actuarial report prepared by such Old Kent Benefit
Plan's actuary with respect to such Old Kent Benefit Plan, did not, as of its

3(26) of ERISA) of the assets of such Old Kent Benefit Plan allocable to such
accrued benefits, (iv) no Old Kent Benefit Plan provides benefits coverage,
including, without limitation, death or medical benefits coverage (whether or
not insured), with respect to current or former employees or directors of Old
Kent or its Subsidiaries beyond their retirement or other termination of

cost of which is borne by the current or former employee or director (or his
beneficiary), (E) coverage through the last day of the calendar month in which
retirement or other termination of service occurs, or (F) medical expense

incurred by Old Kent, its Subsidiaries or any Old Kent ERISA Affiliate that has
not

                                       16
<PAGE>   24
been satisfied in full, and no condition exists that presents a material risk to
Old Kent, its Subsidiaries or any Old Kent ERISA Affiliate of incurring a
liability thereunder, (vi) no Old Kent Benefit Plan is a "multiemployer pension
plan" (as such term is defined in Section 3(37) of ERISA), (vii) none of Old
Kent, its Subsidiaries or any other person, including any fiduciary, has engaged
in a transaction in connection with which Old Kent, its Subsidiaries or any Old
Kent Benefit Plan will be subject to either a material civil penalty assessed
pursuant to Section 409 or 502(i) of ERISA or a material Tax imposed pursuant to
Section 4975 or 4976 of the Code, (viii) to the best knowledge of Old Kent there
are no pending, threatened or anticipated claims (other than routine claims for
benefits) by, on behalf of or against any of the Old Kent Benefit Plans or any
trusts related thereto that will have, either individually or in the aggregate,
a Material Adverse Effect on Old Kent, (x) no employee, former employee, plan
participant or any other party (other than Company) has any entitlement (under
the terms of any plan document or otherwise) to any surplus assets in any
defined benefit plan as defined in Section 414(j) of the Code and (xi) Company
has all power and authority necessary to amend or terminate each Benefit Plan
without incurring any penalty or liability provided that, in the case of an
employee pension benefit plan (as defined in section 3(2) of ERISA), benefits
accrued as of the date of amendment or termination are not reduced.

                  (d) Neither the execution and delivery of this Agreement nor
the consummation of the transactions contemplated hereby will (either alone or
in conjunction with any other event) (i) result in any payment (including,
without limitation, severance, unemployment compensation, "excess parachute
payment" (within the meaning of Section 280G of the Code), forgiveness of
indebtedness or otherwise) becoming due to any director or any employee of Old
Kent or any of its affiliates from Old Kent or any of its affiliates under any
Old Kent Benefit Plan or otherwise, (ii) increase any benefits otherwise payable
under any Old Kent Benefit Plan or (iii) result in any acceleration of the time
of payment or vesting of any such benefits.

                  3.12 SEC Reports. Old Kent has previously made available to
Fifth Third an accurate and complete copy of each (a) final registration
statement, prospectus, report, schedule and definitive proxy statement filed
since January 1, 1997 by Old Kent with the SEC pursuant to the Securities Act of
1933, as amended (the "Securities Act"), or the Exchange Act (the "Old Kent
Reports") and prior to the date hereof and (b) communication mailed by Old Kent
to its stockholders since January 1, 1997 and prior to the date hereof, and no
such Old Kent Report or communication, as of the date thereof, contained any
untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances in which they were made, not misleading,
except that information as of a later date (but before the date hereof) shall be
deemed to modify information as of an earlier date. Since January 1, 1997, as of
their respective dates, all Old Kent Reports filed under the Securities Act and
the Exchange Act complied in all material respects with the published rules and
regulations of the SEC with respect thereto.

                                       17
<PAGE>   25
                  3.13 Compliance with Applicable Law. (a) Old Kent and each of
its Subsidiaries hold all material licenses, franchises, permits and
authorizations necessary for the lawful conduct of their respective businesses
under and pursuant to each, and have complied in all material respects with and
are not in default in any material respect under any, applicable law, statute,
order, rule, regulation, policy and/or guideline of any Governmental Entity
relating to Old Kent or any of its Subsidiaries, except where the failure to
hold such license, franchise, permit or authorization or such noncompliance or
default will not, either individually or in the aggregate, have a Material
Adverse Effect on Old Kent.

                  (b) Except as will not have, either individually or in the
aggregate, a Material Adverse Effect on Old Kent, Old Kent and each Old Kent
Subsidiary have properly administered all accounts for which it acts as a
fiduciary, including accounts for which it serves as a trustee, agent,
custodian, personal representative, guardian, conservator or investment advisor,
in accordance with the terms of the governing documents, applicable state and
federal law and regulation and common law. None of Old Kent, any Old Kent
Subsidiary, or any director, officer or employee of Old Kent or of any Old Kent
Subsidiary, has committed any breach of trust with respect to any such fiduciary
account that will have a Material Adverse Effect on Old Kent, and the
accountings for each such fiduciary account are true and correct in all material
respects and accurately reflect the assets of such fiduciary account.

                  3.14 Certain Contracts. (a) Neither Old Kent nor any of its
Subsidiaries is a party to or bound by any contract, arrangement, commitment or
understanding (whether written or oral) (i) with respect to the employment of
any directors, officers or employees, other than in the ordinary course of
business consistent with past practice, (ii) which, upon the consummation or
stockholder approval of the transactions contemplated by this Agreement will
(either alone or upon the occurrence of any additional acts or events) result in
any payment (whether of severance pay or otherwise) becoming due from Fifth
Third, Old Kent, the Surviving Corporation, or any of their respective
Subsidiaries to any officer or employee thereof, (iii) which is a "material
contract" (as such term is defined in Item 601(b)(10) of Regulation S-K of the
SEC) to be performed after the date of this Agreement that has not been filed or
incorporated by reference in the Old Kent Reports, (iv) which materially
restricts the conduct of any line of business by Old Kent or upon consummation
of the Merger will materially restrict the ability of the Surviving Corporation
to engage in any line of business in which a bank holding company may lawfully
engage, (v) with or to a labor union or guild (including any collective
bargaining agreement) or (vi) (including any stock option plan, stock
appreciation rights plan, restricted stock plan or stock purchase plan) any of
the benefits of which will be increased, or the vesting of the benefits of which
will be accelerated, by the occurrence of any stockholder approval or the
consummation of any of the transactions contemplated by this Agreement, or the
value of any of the benefits of which will be calculated on the basis of any of
the transactions contemplated by this Agreement. Old Kent has previously made
available to Fifth Third true and correct copies of all employment and deferred
compensation agreements which are in writing and to which Old Kent or any of its
Subsidiaries is a party. Each contract, arrangement,

                                       18
<PAGE>   26
commitment or understanding of the type described in this Section 3.14(a),
whether or not set forth in the Old Kent Disclosure Schedule, is referred to
herein as a "Old Kent Contract," and neither Old Kent nor any of its
Subsidiaries knows of, or has received notice of, any violation of the above by
any of the other parties thereto which, either individually or in the aggregate,
will have a Material Adverse Effect on Old Kent.

                  (b) With such exceptions that, either individually or in the
aggregate, will not have a Material Adverse Effect on Old Kent, (i) each Old
Kent Contract is valid and binding on Old Kent or any of its Subsidiaries, as
applicable, and is in full force and effect, (ii) Old Kent and each of its
Subsidiaries has in all material respects performed all obligations required to
be performed by it to date under each Old Kent Contract, and (iii) no event or
condition exists which constitutes or, after notice or lapse of time or both,
will constitute, a material default on the part of Old Kent or any of its
Subsidiaries under any such Old Kent Contract.

                  3.15 Agreements with Regulatory Agencies. Neither Old Kent nor
any of its Subsidiaries is subject to any cease-and-desist or other order or
enforcement action issued by, or is a party to any written agreement, consent
agreement or memorandum of understanding with, or is a party to any commitment
letter or similar undertaking to, or is subject to any order or directive by, or
has been ordered to pay any civil money penalty by, or has been since January 1,
1997, a recipient of any supervisory letter from, or since January 1, 1997, has
adopted any policies, procedures or board resolutions at the request or
suggestion of any Regulatory Agency or other Governmental Entity that currently
restricts in any material respect the conduct of its business or that in any
material manner relates to its capital adequacy, its ability to pay dividends,
its credit or risk management policies, its management or its business (each
item in this sentence, whether or not set forth in the Old Kent Disclosure
Schedule, a "Old Kent Regulatory Agreement"), nor has Old Kent or any of its
Subsidiaries been advised since January 1, 1997, by any Regulatory Agency or
other Governmental Entity that it is considering issuing, initiating, ordering,
or requesting any such Old Kent Regulatory Agreement.

                  3.16 Interest Rate Risk Management Instruments. All interest
rate swaps, caps, floors and option agreements and other interest rate risk
management arrangements, whether entered into for the account of Old Kent or for
the account of a customer of Old Kent or any of its Subsidiaries, were entered
into in the ordinary course of business consistent with past practice and, to
Old Kent's knowledge, in accordance with prudent banking practice and applicable
rules, regulations and policies of any Regulatory Authority and with
counterparties believed to be financially responsible at the time and are legal,
valid and binding obligations of Old Kent or one of its Subsidiaries enforceable
in accordance with their terms (except as may be limited by bankruptcy,
insolvency, moratorium, reorganization or similar laws affecting the rights of
creditors generally and the availability of equitable remedies), and are in full
force and effect. Old Kent and each of its Subsidiaries have duly performed in
all material respects all of their material obligations thereunder to the extent
that such obligations to perform have accrued; and, to Old Kent's knowledge,
there are no material breaches, violations or defaults or allegations or
assertions of such by any party thereunder.

                                       19
<PAGE>   27
                  3.17 Undisclosed Liabilities. Except for those liabilities
that are fully reflected or reserved against on the consolidated balance sheet
of Old Kent included in the Old Kent 1999 10-K and for liabilities incurred in
the ordinary course of business consistent with past practice since December 31,
1999, since such date, neither Old Kent nor any of its Subsidiaries has incurred
any liability of any nature whatsoever (whether absolute, accrued, contingent or
otherwise and whether due or to become due) that, either individually or in the
aggregate (including if considered together with liabilities incurred in the
ordinary course of business consistent with past practice since December 31,
1999), has had or will have a Material Adverse Effect on Old Kent.

                  3.18 Environmental Liability. There are no legal,
administrative, arbitral or other proceedings, claims, actions, causes of
action, private environmental investigations or remediation activities or
governmental investigations of any nature seeking to impose, or that could
reasonably result in the imposition, on Old Kent of any liability or obligation
arising under common law or under any local, state or federal environmental
statute, regulation or ordinance including, without limitation, the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, pending or threatened against Old Kent, which liability or obligation
will, either individually or in the aggregate, have a Material Adverse Effect on
Old Kent. To the knowledge of Old Kent, there is no reasonable basis for any
such proceeding, claim, action or governmental investigation that would impose
any liability or obligation that will, individually or in the aggregate, have a
Material Adverse Effect on Old Kent. Old Kent is not subject to any agreement,
order, judgment, decree, letter or memorandum by or with any Governmental
Authority or third party imposing any liability or obligation with respect to
the foregoing that will have, either individually or in the aggregate, a
Material Adverse Effect on Old Kent.

                  3.19 Intellectual Property. Except as would not reasonably be
expected to have a Material Adverse Effect on Old Kent, to the knowledge of Old
Kent: (a) Old Kent and each of its Subsidiaries owns, or is licensed to use (in
each case, free and clear of any liens), all Intellectual Property (as defined
below) used in or necessary for the conduct of its business as currently
conducted; (b) the use of any Intellectual Property by Old Kent and its
Subsidiaries does not infringe on or otherwise violate the rights of any person
and is in accordance with any applicable license pursuant to which Old Kent or
any Subsidiary acquired the right to use any Intellectual Property; (c) no
Person is challenging, infringing on or otherwise violating any right of Old
Kent or any of its Subsidiaries with respect to any Intellectual Property owned
by and/or licensed to Old Kent or its Subsidiaries; and (d) neither Old Kent nor
any of its Subsidiaries has received any written notice of any pending claim
with respect to any Intellectual Property used by Old Kent and its Subsidiaries
and no Intellectual Property owned and/or licensed by Old Kent or its
Subsidiaries is being used or enforced in a manner that would result in the
abandonment, cancellation or unenforceability of such Intellectual Property. For
purposes of this Agreement, "Intellectual Property" shall mean trademarks,
service marks, brand names, certification marks, trade dress and other
indications of origin, the goodwill associated with the foregoing and
registrations in any jurisdiction of, and applications in any jurisdiction to
register, the foregoing,

                                       20
<PAGE>   28
including any extension, modification or renewal of any such registration or
application; inventions, discoveries and ideas, whether patentable or not, in
any jurisdiction; patents, applications for patents (including, without
limitation, divisions, continuations, continuations in part and renewal
applications), and any renewals, extensions or reissues thereof, in any
jurisdiction; nonpublic information, trade secrets and confidential information
and rights in any jurisdiction to limit the use or disclosure thereof by any
person; writings and other works, whether copyrightable or not, in any
jurisdiction; and registrations or applications for registration of copyrights
in any jurisdiction, and any renewals or extensions thereof; any similar
intellectual property or proprietary rights.

                  3.20 State Takeover Laws; Old Kent Rights Agreement. (a) The
Board of Directors of Old Kent has approved this Agreement and the Old Kent
Option Agreement and the transactions contemplated hereby and thereby for
purposes of rendering inapplicable to such agreements and transactions the
Michigan Control Share Acquisitions statute (Chapter 7B of the MBCA), Section
780 of the MBCA, the Old Kent Rights Agreement, Article XII of the Old Kent
Articles and, to the best knowledge of Old Kent, any similar "takeover" or
"interested stockholder" law (all such laws, including the Michigan Control
Share Acquisitions statute (Chapter 7B of the MBCA) and Section 780 of the MBCA,
"Takeover Statutes").

                  (b) Old Kent has taken all action, if any, necessary or
appropriate so that the entering into of this Agreement and the Old Kent Option
Agreement, and the consummation of the transactions contemplated hereby and
thereby do not and will not result in the ability of any person to exercise any
Old Kent Stockholder Rights under the Old Kent Rights Agreement or enable or
require Old Kent Stockholder Rights to separate from the shares of Old Kent
Common Stock to which they are attached or to be triggered or become
exercisable. No "Triggering Event" or "Stock Acquisition Date" (as such terms
are defined in the Old Kent Rights Agreement) has occurred.

                  3.21 Reorganization; Pooling of Interests. As of the date of
this Agreement, Old Kent has no reason to believe that the Merger will not
qualify as a "reorganization" within the meaning of Section 368(a) of the Code
and as a "pooling of interests" for accounting purposes.

                  3.22 Opinions. Prior to the execution of this Agreement, Old
Kent has received an opinion from Merrill Lynch & Co. to the effect that as of
the date thereof and based upon and subject to the matters set forth therein,
the Exchange Ratio is fair to the stockholders of Old Kent from a financial
point of view. Such opinion has not been amended or rescinded as of the date of
this Agreement.

                  3.23 Old Kent Information. The information relating to Old
Kent and its Subsidiaries which is provided by Old Kent or its representatives
for inclusion in the Joint Proxy Statement and the S-4, or in any other document
filed with any other Regulatory Agency in connection herewith, will not contain
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances in which
they are made, not misleading. The Joint Proxy

                                       21
<PAGE>   29
Statement (except for such portions thereof that relate only to Fifth Third or
any of its Subsidiaries) will comply with the provisions of the Exchange Act and
the rules and regulations thereunder.

                  3.24 Loan Losses. Since December 31, 1999, none of the bank
Subsidiaries of Old Kent (the "Old Kent Bank Subsidiaries") has incurred any
unusual or extraordinary loan losses which are material to Old Kent and the Old
Kent Subsidiaries on a consolidated basis; to the best knowledge of Old Kent and
in light of each of the Old Kent Bank Subsidiaries' historical loan loss
experience and its management's analysis of the quality and performance of its
loan portfolio, as of December 31, 1999, its reserves for loan losses are
adequate to absorb potential loan losses determined on the basis of management's
continuing review and evaluation of the loan portfolio and its judgment as to
the impact of economic conditions on the portfolio.

                                   ARTICLE IV


                  REPRESENTATIONS AND WARRANTIES OF FIFTH THIRD

all of its properties and assets and to carry on its business as it is now being
conducted, and is duly licensed or qualified to do business in each jurisdiction
in which the nature of the business conducted by it or the character or location
of the properties and assets owned or leased by it makes such licensing or
qualification necessary, except where the failure to be so licensed or qualified
would not, either individually or in the aggregate, have a Material Adverse
Effect on Fifth Third. Fifth Third was certified as an FHC under the BHC Act,
and remains a certified FHC on the date hereof. True and complete copies of the
Second Amended Articles of Incorporation (the "Fifth Third Articles") and the
Code of Regulations of Fifth Third, as in effect as of the date of this
Agreement, have previously been made available by Fifth Third to Old Kent.

                  (b) Each Fifth Third Subsidiary (i) is duly organized and
validly existing under the laws of its jurisdiction of organization, (ii) is
duly qualified to do business and in good standing in all jurisdictions (whether
Federal, state, local or foreign) where its ownership or leasing of property or
the conduct of its business requires it to be so qualified and in which the
failure to be so qualified would have a Material Adverse Effect on Fifth Third,
and (iii) has all requisite corporate power and authority to own or lease its
properties and assets and to carry on its business as now conducted.

and all of such shares or equity ownership interests are duly authorized and
validly issued and are fully paid, nonassessable (subject to 12 U.S.C. Sections
55) and free of preemptive rights, with no personal liability attaching to the
ownership thereof. No Fifth Third Subsidiary has or is bound by any outstanding
subscriptions, options, warrants, calls, commitments or agreements of any
character calling for the purchase or issuance of any shares of capital stock or
any other equity security of such Subsidiary or any securities representing the
right to purchase or otherwise receive any shares of capital stock or any other
equity security of such Subsidiary.

                  4.3 Authority, No Violation. (a) Fifth Third has full
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby. The execution and delivery of

obligations of Fifth Third, enforceable against Fifth Third in accordance with
its terms (except as may be limited by bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting the rights of creditors generally and
the availability of equitable remedies).

                  (b) Neither the execution and delivery of this Agreement by
Fifth Third, nor the consummation by Fifth Third of the transactions

provisions hereof, will (i) violate any provision of the Fifth Third Articles or
Code of Regulations, or (ii) assuming that the consents and approvals referred

Fifth Third, any of its Subsidiaries is a party, or by which they or any of
their respective properties or assets may be bound or affected, except (in the
case of clause (y) above) for such violations, conflicts, breaches or defaults
which either individually or in the aggregate will not have a Material Adverse
Effect on Fifth Third.

and the other transactions contemplated hereby.

                  4.5 Reports. Fifth Third and each of its Subsidiaries have
timely filed all reports, registrations and statements, together with any
amendments required to be made with respect thereto, that they were required to
file since January 1, 1997 with the Regulatory Agencies, and all other reports
and statements required to be filed by them since January 1, 1997, including,
without limitation, any report or statement required to be filed pursuant to the
laws, rules or regulations of the United States, any state, any foreign entity
or any Regulatory Agency, and have paid all fees and assessments due and payable
in connection therewith, except where the failure to file such report,
registration or statement or to pay such fees and assessments, either
individually or in the aggregate, will not have a Material Adverse Effect on
Fifth Third. Except for normal examinations conducted by a Regulatory Agency in
the ordinary course of the business of Fifth Third and its Subsidiaries, no
Regulatory Agency has initiated or has pending any proceeding or, to the best
knowledge of Fifth Third, investigation into the business or operations of Fifth
Third or any of its Subsidiaries since January 1, 1997, except where such
proceedings or investigation will not have, either individually or in the
aggregate, a Material Adverse Effect on Fifth Third. There (i) is no unresolved
violation, criticism, or exception by any Regulatory Agency with respect to any
report or statement relating to any examinations or inspections of Fifth Third
or any of its Subsidiaries, and (ii) has been no formal or informal inquiries
by, or disagreements or disputes with, any Regulatory Agency with respect to the
business, operations, policies or procedures of Fifth Third since January 1,
1997, which, in the reasonable judgment of Fifth Third, will have, either
individually or in the aggregate, a Material Adverse Effect on Fifth Third.

                  4.6 Financial Statements. Fifth Third has previously provided
to Old Kent copies of (i) the audited consolidated balance sheets of Fifth Third
and its Subsidiaries as of December 31, for the fiscal years 1998 and 1999, and
the related audited consolidated statements of income, changes in stockholders'
equity and cash flows for the fiscal years 1997 through 1999, inclusive (the
"Fifth Third 1999 Financial Information"), as reported in Fifth Third's Annual
Report on Form 10-K for the fiscal year ended December 31, 1999 (the "Fifth
Third 1999 10-K") filed with the SEC under the Exchange Act, accompanied by the
audit report of Deloitte & Touche LLP, independent public accountants with
respect to Fifth Third and (ii) the unaudited consolidated balance sheet of
Fifth Third and its Subsidiaries as of September 30, 1999 and 2000, and the
related consolidated statements of income, changes in shareholders' equity and
cash flows of the nine month periods then ended, as reported in Fifth Third's
Quarterly Report on Form 10-Q for the fiscal period ended September 30, 2000.
The

                                       25
<PAGE>   33
December 31, 1999 consolidated balance sheet of Fifth Third (including the
related notes, where applicable) fairly presents in all material respects the
consolidated financial position of Fifth Third and its Subsidiaries as of the
date thereof, and the other financial statements referred to in this Section 4.6
(including the related notes, where applicable) fairly present in all material
respects the results of the consolidated operations and changes in stockholders'
equity and consolidated financial position of Fifth Third and its Subsidiaries
for the respective fiscal periods or as of the respective dates therein set
forth, subject to normal year-end audit adjustments in amounts consistent with
past experience in the case of unaudited statements; each of such statements
(including the related notes, where applicable) complies in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto; and each of such statements
(including the related notes, where applicable) has been prepared in all
material respects in accordance with GAAP consistently applied during the
periods involved, except in each case as indicated in such statements or in the
notes thereto. The books and records of Fifth Third and its Subsidiaries have
been, and are being, maintained in all material respects in accordance with GAAP
and any other applicable legal and accounting requirements and reflect only
actual transactions.

                  4.7 Broker's Fees. Neither Fifth Third nor any Fifth Third
Subsidiary nor any of their respective officers or directors has employed any
broker or finder or incurred any liability for any brokers fees, commissions or
finder's fees other than fees payable to Salomon Smith Barney, Inc. in
connection with the Merger or related transactions contemplated by this
Agreement.

                  4.8 Absence of Certain Changes or Events. (a) Since December
31, 1999, no event or events have occurred which has had, individually or in the
aggregate, a Material Adverse Effect on Fifth Third.

                  (b) From December 31, 1999 through and including the date
hereof, Fifth Third and the Fifth Third Subsidiaries have carried on their
respective businesses in all material respect in the ordinary course.

                  4.9 Legal Proceedings. (a) Neither Fifth Third nor any of its
Subsidiaries is a party to any, and there are no pending or, to the best of
Fifth Third's knowledge, threatened, legal, administrative, arbitral or other
proceedings, claims, actions or governmental or regulatory investigations of any
nature against Fifth Third or any of its Subsidiaries or challenging the
validity or propriety of the transactions contemplated by this Agreement as to
which, in any such case, there is a reasonable probability of an adverse
determination and which, if adversely determined, will have, either individually
or in the aggregate, a Material Adverse Effect on Fifth Third.

                  (b) There is no Injunction, judgment, or regulatory
restriction (other than those of general application that apply to similarly
situated bank holding companies or their Subsidiaries) imposed upon Fifth Third,
any of its Subsidiaries or the assets of Fifth Third or any of its Subsidiaries
that has had or will have, either

                                       26
<PAGE>   34
individually or in the aggregate, a Material Adverse Effect on Fifth Third or
the Surviving Corporation.

                  4.10 Taxes and Tax Returns. Each of Fifth Third and its
Subsidiaries has duly filed all federal, state, foreign and local information
returns and Tax returns required to be filed by it on or prior to the date
hereof (all such returns being accurate and complete in all material respects)
and has duly paid or made provision for the payment of all Taxes and other
governmental charges which have been incurred or are due or claimed to be due
from it by federal, state, foreign or local taxing authorities (including,
without limitation, if and to the extent applicable, those due in respect of its
properties, income, business, capital stock, deposits, franchises, licenses,
sales and payrolls) other than (i) Taxes or other governmental charges which are
not yet delinquent or are being contested in good faith and have not been
finally determined, or (ii) information returns, tax returns, Taxes or other
governmental charges as to which the failure to file, pay or make provision for
will not have, either individually or in the aggregate, a Material Adverse
Effect on Fifth Third. The federal income Tax returns of Fifth Third and its
Subsidiaries have been examined by the IRS through 1990 and any liability with
respect thereto has been satisfied or any liability with respect to deficiencies
asserted as a result of such examination is covered by adequate reserves. There
are no material disputes pending, or claims asserted for, Taxes or assessments
upon Fifth Third or any of its Subsidiaries for which Fifth Third does not have
adequate reserves maintained in accordance with GAAP. Neither Fifth Third nor
any of its Subsidiaries is a party to or is bound by any Tax sharing, allocation
or indemnification agreement or arrangement (other than such an agreement or
arrangement exclusively between or among Fifth Third and its Subsidiaries).
Within the past five years, neither Fifth Third nor any of its Subsidiaries has
been a "distributing corporation" or a "controlled corporation" in a
distribution intended to qualify under Section 355(a) of the Code.

                  (b) No disallowance of a deduction under Section 162(m) of the
Code for employee remuneration of any amount paid or payable by Fifth Third or
any of its Subsidiaries under any contract, plan, program, arrangement or
understanding would be reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Fifth Third.

                  4.11 SEC Reports. Fifth Third has previously made available to
Old Kent an accurate and complete copy of each (a) final registration statement,
prospectus, report, schedule and definitive proxy statement filed since January
1, 1997 by Fifth Third with the SEC pursuant to the Securities Act or the
Exchange Act (the "Fifth Third Reports") and prior to the date hereof and (b)
communication mailed by Fifth Third to its stockholders since January 1, 1997
and prior to the date hereof, and no such Fifth Third Report or communication,
as of the date thereof, contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances in which
they were made, not misleading, except that information as of a later date (but
before the date hereof) shall be deemed to modify information as of an earlier
date. Since

                                       27
<PAGE>   35
January 1, 1997, as of their respective dates, all Fifth Third Reports filed
under the Securities Act and the Exchange Act complied in all material respects
with the published rules and regulations of the SEC with respect thereto.

                  4.12 Compliance with Applicable Law. (a) Fifth Third and each
of its Subsidiaries hold all material licenses, franchises, permits and
authorizations necessary for the lawful conduct of their respective businesses
under and pursuant to each, and have complied in all material respects with and
are not in default in any material respect under any, applicable law, statute,
order, rule, regulation, policy and/or guideline of any Governmental Entity
relating to Fifth Third or any of its Subsidiaries, except where the failure to
hold such license, franchise, permit or authorization or such noncompliance or
default will not, either individually or in the aggregate, have a Material
Adverse Effect on Fifth Third.

                  (b) Except as will not have, either individually or in the
aggregate, a Material Adverse Effect on Fifth Third, Fifth Third and each Fifth
Third Subsidiary have properly administered all accounts for which it acts as a
fiduciary, including accounts for which it serves as a trustee, agent,
custodian, personal representative, guardian, conservator or investment advisor,
in accordance with the terms of the governing documents, applicable state and
federal law and regulation and common law. None of Fifth Third, any Fifth Third
Subsidiary, or any director, officer or employee of Fifth Third or of any Fifth
Third Subsidiary, has committed any breach of trust with respect to any such
fiduciary account that will have a Material Adverse Effect on Fifth Third, and
the accountings for each such fiduciary account are true and correct in all
material respects and accurately reflect the assets of such fiduciary account.

                  4.13 Agreements with Regulatory Agencies. Neither Fifth Third
nor any of its Subsidiaries is subject to any cease-and-desist or other order or
enforcement action issued by, or is a party to any written agreement, consent
agreement or memorandum of understanding with, or is a party to any commitment
letter or similar undertaking to, or is subject to any order or directive by, or
has been since January 1, 1997, a recipient of any supervisory letter from, or
has been ordered to pay any civil money penalty by, or since January 1, 1997,
has adopted any policies, procedures or board resolutions at the request of any
Regulatory Agency or other Governmental Entity that currently restricts in any
material respect the conduct of its business or that in any material manner
relates to its capital adequacy, its ability to pay dividends, its credit or
risk management policies, its management or its business (each, whether or not
set forth in the Fifth Third Disclosure Schedule, a "Fifth Third Regulatory
Agreement"), nor has Fifth Third or any of its Subsidiaries been advised since
January 1, 1997, by any Regulatory Agency or other Governmental Entity that it
is considering issuing, initiating, ordering or requesting any such Fifth Third
Regulatory Agreement.

                  4.14 Interest Rate Risk Management Instruments. All interest
rate swaps, caps, floors and option agreements and other interest rate risk
management arrangements, whether entered into for the account of Fifth Third or
for the account of a customer of Fifth Third or one of its Subsidiaries, were
entered into in the ordinary

                                       28
<PAGE>   36
course of business consistent with past practice and, to Fifth Third's
knowledge, in accordance with prudent banking practice and applicable rules,
regulations and policies of any Regulatory Authority and with counterparties
believed to be financially responsible at the time and are legal, valid and
binding obligations of Fifth Third or one of its Subsidiaries enforceable in
accordance with their terms (except as may be limited by bankruptcy, insolvency,
moratorium, reorganization or similar laws affecting the rights of creditors
generally and the availability of equitable remedies), and are in full force and
effect. Fifth Third and each of its Subsidiaries have duly performed in all
material respects all of their material obligations thereunder to the extent
that such obligations to perform have accrued; and to Fifth Third's knowledge,
there are no material breaches, violations or defaults or allegations or
assertions of such by any party thereunder.

                  4.15 Undisclosed Liabilities. Except for those liabilities
that are fully reflected or reserved against on the consolidated balance sheet
of Fifth Third included in the Fifth Third 1999 Financial Information and for
liabilities incurred in the ordinary course of business consistent with past
practice since December 31, 1999, since such date, neither Fifth Third nor any
of its Subsidiaries has incurred any liability of any nature whatsoever (whether
absolute, accrued, contingent or otherwise and whether due or to become due)
that, either individually or in the aggregate (including if considered together
with liabilities incurred in the ordinary course of business consistent with
past practice since December 31, 1999), has had or will have, a Material Adverse
Effect on Fifth Third.

                  4.16 Environmental Liability. There are no legal,
administrative, arbitral or other proceedings, claims, actions, causes of
action, private environmental investigations or remediation activities or
governmental investigations of any nature seeking to impose, or that could
reasonably result in the imposition, on Fifth Third of any liability or
obligation arising under common law or under any local, state or federal
environmental statute, regulation or ordinance including, without limitation,
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, pending or threatened against Fifth Third, which liability or
obligation will, either individually or in the aggregate, have a Material
Adverse Effect on Fifth Third. To the knowledge of Fifth Third, there is no
reasonable basis for any such proceeding, claim, action or governmental
investigation that would impose any liability or obligation that will,
individually or in the aggregate, have a Material Adverse Effect on Fifth Third.
Fifth Third is not subject to any agreement, order, judgment, decree, letter or
memorandum by or with any Governmental Authority or third party imposing any
liability or obligation with respect to the foregoing that will have, either
individually or in the aggregate, a Material Adverse Effect on Fifth Third.

                  4.17 Reorganization; Pooling of Interests. As of the date of
this Agreement, Fifth Third has no reason to believe that the Merger will not
qualify as a "reorganization" within the meaning of Section 368(a) of the Code
and as a "pooling of interests" for accounting purposes.

                                       29
<PAGE>   37
                  4.18 Fifth Third Information. The information relating to
Fifth Third and its Subsidiaries to be contained in the Joint Proxy Statement
and the S-4, or the information relating to Fifth Third and its Subsidiaries
that is provided by Fifth Third or its representatives for inclusion in any
other document filed with any other Regulatory Agency in connection herewith,
will not contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in light of the
circumstances in which they are made, not misleading. The Joint Proxy Statement
(except for such portions thereof that relate only to Old Kent or any of its
Subsidiaries) will comply with the provisions of the Exchange Act and the rules
and regulations thereunder. The S-4 will comply with the provisions of the
Securities Act and the rules and regulations thereunder.

                  4.19 Loan Losses. Since December 31, 1999, none of the bank
Subsidiaries of Fifth Third (the "Fifth Third Bank Subsidiaries") has incurred
any unusual or extraordinary loan losses which are material to Fifth Third and
the Fifth Third Subsidiaries on a consolidated basis; to the best knowledge of
Fifth Third and in light of each of the Fifth Third Bank Subsidiaries'
historical loan loss experience and its management's analysis of the quality and
performance of its loan portfolio, as of December 31, 1999, its reserves for
loan losses are adequate to absorb potential loan losses determined on the basis
of management's continuing review and evaluation of the loan portfolio and its
judgment as to the impact of economic conditions on the portfolio.

required to carry out the transactions contemplated by this Agreement, and Old

                  (b) The parties hereto shall cooperate with each other and use
their reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, to

<PAGE>   42
all permits, consents, approvals and authorizations of all third parties and
Governmental Entities which are necessary or advisable to consummate the
transactions contemplated by this Agreement (including, without limitation, the
Merger), and to comply with the terms and conditions of all such permits,
consents, approvals and authorizations of all such Governmental Entities. Fifth
Third and Old Kent shall have the right to review in advance, and, to the extent
practicable, each will consult the other on, in each case subject to applicable
laws relating to the exchange of information, all the information relating to
Old Kent or Fifth Third, as the case may be, and any of their respective
Subsidiaries, which appear in any filing made with, or written materials
submitted to, any third party or any Governmental Entity in connection with the
transactions contemplated by this Agreement. In exercising the foregoing right,
each of the parties hereto shall act reasonably and as promptly as practicable.
The parties hereto agree that they will consult with each other with respect to
the obtaining of all permits, consents, approvals and authorizations of all
third parties and Governmental Entities necessary or advisable to consummate the

                  (c) Fifth Third and Old Kent shall, upon request, furnish each
other with all information concerning themselves, their Subsidiaries, directors,

Old Kent or any of their respective Subsidiaries to any Governmental Entity in
connection with the Merger and the other transactions contemplated by this
Agreement.

                  (d) Fifth Third and Old Kent shall promptly advise each other
upon receiving any communication from any Governmental Entity whose consent or
approval is required for consummation of the transactions contemplated by this
Agreement that causes such party to believe that there is a reasonable
likelihood that any Requisite Regulatory Approval will not be obtained or that
the receipt of any such approval will be materially delayed.

                  6.2 Access to Information. (a) Upon reasonable notice and
subject to applicable laws relating to the exchange of information, the parties
shall, and shall cause each of its Subsidiaries to, afford to the officers,
employees, accountants, counsel and other representatives of the other party,
access, during normal business hours during the period prior to the Effective
Time, to all its properties, books, contracts, commitments and records, and,
during such period, the parties shall, and shall cause its Subsidiaries to, make
available to the other party (i) a copy of each report, schedule, registration
statement and other document filed or received by it during such period pursuant
to the requirements of federal securities laws or federal or state banking laws
(other than reports or documents which such party is not permitted to disclose
under applicable law) and (ii) all other information concerning its business,
properties and personnel as the other party may reasonably request. None of the
parties nor any of their Subsidiaries shall be required to provide access to or
to disclose information where

                                       35
<PAGE>   43
such access or disclosure would jeopardize the attorney-client privilege of such
party or its Subsidiaries or contravene any law, rule, regulation, order,
judgment, decree, fiduciary duty or binding agreement entered into prior to the
date of this Agreement. The parties hereto will make appropriate substitute
disclosure arrangements under circumstances in which the restrictions of the
preceding sentence apply.

                  (b) Except as provided in Section 9.9, each party to this
Agreement shall hold, and shall cause its respective Subsidiaries and its and
its Subsidiaries' directors, officers, employees, agents, consultants and
advisors to hold, all information furnished by or on behalf of the other party
or any of such party's Subsidiaries or representatives pursuant to Section
6.2(a) in confidence to the extent required by, and in accordance with, the
provisions of the confidentiality agreement, dated November 14, 2000, between
the parties.

                  (c) No investigation by either of the parties or their

the other set forth herein.

as reasonably practicable, for the purpose of voting upon the requisite
stockholder approvals required in connection with this Agreement and the Merger,
and each shall use its reasonable best efforts to cause such meetings to occur
on such date. The Board of Directors of each of Fifth Third and Old Kent shall
use its reasonable best efforts to obtain from the stockholders of Fifth Third
and Old Kent, as the case may be, the vote in favor of the adoption of this
Agreement required by the MBCA, in the case of Old Kent, and in favor of the
adoption of this Agreement required by the OGCL, the Fifth Third Charter
Amendment and the issuance of shares of Fifth Third Common Stock pursuant to the
Merger, in the case of Fifth Third (it being understood and agreed that the
obligations under this sentence shall not be altered by the commencement,
proposal, disclosure or communication of any Acquisition Transaction (as defined
in the Old Kent Option Agreement)).

                  6.4 Legal Conditions to Merger. Each of Fifth Third and Old
Kent shall, and shall cause its Subsidiaries to, use their reasonable best
efforts (a) to take, or cause to be taken, all actions necessary, proper or
advisable to comply promptly with all legal requirements that may be imposed on
such party or its Subsidiaries with respect to the Merger and, subject to the
conditions set forth in Article VII hereof, to consummate the transactions
contemplated by this Agreement, and (b) to obtain (and to cooperate with the
other party to obtain) any material consent, authorization, order or approval
of, or any exemption by, any Governmental Entity and any other third party that
is required to be obtained by Old Kent or Fifth Third or any of their respective

<PAGE>   44
executive officer and other person who is an "affiliate" (for purposes of Rule
145 under the Securities Act and for purposes of qualifying the Merger for
"pooling of interests" accounting treatment) of such party to deliver to the
other party hereto, as soon as practicable after the date of this Agreement, and
prior to the date of the stockholders' meeting called by Old Kent to approve
this Agreement, a written agreement, in the form of Exhibit 6.5(a)(1) or (2), as
applicable, hereto.

                  (b) The Surviving Corporation shall use its best efforts to

benefits to be provided to employees of Old Kent and its Subsidiaries as of the
Effective Time ("Covered Employees") shall be substantially similar, in the
aggregate, to the benefits provided under the benefit plans and programs
provided by Old Kent or its Subsidiaries, as the case may be, to such employees
as of the date hereof. From and after December 31, 2001, the benefits to be
provided to the Covered Employees shall be the benefit plans (other than Fifth
Third's defined benefit pension plan which has been frozen) and programs
provided to similarly situated employees of Fifth Third. Fifth Third shall, from
and after the Effective Time, (i) comply with Old Kent Benefit Plans and other
contractual commitments of Old Kent to its current and former employees in
accordance with their terms and honor all employee benefit obligations to
current and former employees of Old Kent and its Subsidiaries under Old Kent
Benefit Plans or the applicable contractual commitment, (ii) provide Covered
Employees credit for the most recent period of uninterrupted service (including
any bridging or prior service credit, without regard to whether there has been
an interruption in service, solely to the extent provided by Old Kent and its
Subsidiaries as of the date hereof) with Old Kent or any of its Subsidiaries
(and their predecessors) prior to the Effective Time under employee benefit
plans of Fifth Third or its Subsidiaries (other than Fifth Third's
noncontributory cash balance defined benefit pension plan), (iii) cause any and
all pre-existing condition limitations (to the extent such limitations did not
apply to a pre-existing condition under comparable Old Kent Plans) and
eligibility waiting periods under group health plans of Fifth Third to be waived
with respect to Covered Employees (and their eligible dependents) who become
participants in such group health plans and (iv) assume, or cause its applicable
Subsidiary to assume, all contracts and agreements with employees of Old Kent,
which agreements were entered into prior to the date hereof and which are listed
on Section 5.2 of the Old Kent Disclosure Schedule, and all obligations
thereunder. From and after the Effective Time until December 31, 2001, Fifth
Third shall honor all vacation and paid time off of the Covered Employees
accrued as of the Effective Time, in accordance with Old Kent policy as in
effect on the date hereof. From and after the Effective Time, a Covered Employee
who is terminated (as defined in the

                                       37
<PAGE>   45
applicable Old Kent severance plan or policy as in effect on the date hereof)
during the period commencing at the Effective Time and ending on the 12-month
anniversary thereof shall be entitled to receive the greater of (i) the
severance payments and benefits under the applicable Old Kent severance plan or
policy as in effect on the date hereof (without amendment on or after the
Effective Time) and (ii) the severance payments and benefits under Fifth Third's
severance plan or policy as in effect on the date of termination of such Covered
Employee.

                  (b) Nothing in this Section 6.7 shall be interpreted as
preventing the Surviving Corporation or Fifth Third from amending, modifying or
terminating any Fifth Third Benefit Plans or other contracts, arrangements,
commitments or understandings, in accordance with their terms and applicable
law.

                  6.8 Indemnification; Directors' and Officers' Insurance. (a)
In the event of any threatened or actual claim, action, suit, proceeding or
investigation, whether civil, criminal or administrative, including, without
limitation, any such claim, action, suit, proceeding or investigation in which
any individual who is now, or has been at any time prior to the date of this
Agreement, or who becomes prior to the Effective Time, a director or officer or
employee of Old Kent or any of its Subsidiaries (the "Indemnified Parties"), is,
or is threatened to be, made a party based in whole or in part on, or arising in
whole or in part out of, or pertaining to (i) the fact that he is or was a
director, officer or employee of Old Kent or any of its Subsidiaries or (ii)
this Agreement, the Old Kent Option Agreement or any of the transactions
contemplated hereby or thereby, whether in any case asserted or arising before
or after the Effective Time, the parties hereto agree to cooperate and use their
best efforts to defend against and respond thereto. It is understood and agreed
that after the Effective Time, Fifth Third shall indemnify and hold harmless, as
and to the fullest extent provided by applicable law, the Old Kent Articles, the
Old Kent Bylaws and any agreement existing as of the date hereof, each such
Indemnified Party against any losses, claims, damages, liabilities, costs,
expenses (including reimbursement for reasonable fees and expenses incurred in
advance of the final disposition of any claim, suit, proceeding or investigation
to each Indemnified Party as provided by the Old Kent Articles, the Old Kent
Bylaws and any agreement existing as of the date hereof), judgments, fines and
amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding or investigation.

                  (b) Fifth Third shall use its reasonable best efforts to cause
the individuals serving as officers and directors of Old Kent or any of its
Subsidiaries immediately prior to the Effective Time to be covered for a period
of six (6) years from the Effective Time by the directors' and officers'
liability insurance policy maintained by Old Kent (provided that Fifth Third may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are not less advantageous than such
policy) with respect to acts or omissions occurring prior to the Effective Time
which were committed by such officers and directors in their capacity as such;
provided that in no event shall Fifth Third be required to expend in any one
year an amount in excess of 200% of the annual premiums currently paid by Old
Kent (which current

                                       38
<PAGE>   46
amount is set forth in Section 6.8 of the Old Kent Disclosure Schedule) for such
insurance (the "Insurance Amount"), and provided further that if Fifth Third is
unable to maintain such policy (or such substitute policy) as a result of the
preceding proviso, Fifth Third shall use its reasonable best efforts to obtain
as much comparable insurance as is available for the Insurance Amount.

                  (c) The provisions of this Section 6.8 shall survive the
Effective Time and are intended to be for the benefit of, and shall be
enforceable by, each Indemnified Party and his or her heirs and representatives.

                  6.9 Additional Agreements. In case at any time after the
Effective Time any further action is necessary or desirable to carry out the
purposes of this Agreement (including, without limitation, any merger between a
Subsidiary of Fifth Third, on the one hand, and a Subsidiary of Old Kent, on the
other) or to vest the Surviving Corporation with full title to all properties,
assets, rights, approvals, immunities and franchises of any of the parties to
the Merger, the proper officers and directors of each party to this Agreement
and their respective Subsidiaries shall take all such necessary action as may be
reasonably requested by, and at the sole expense of, Fifth Third.

                  6.10 Advice of Changes. Fifth Third and Old Kent shall each
promptly advise the other party of any change or event (i) having a Material
Adverse Effect on it or (ii) which it believes would or would be reasonably
likely to cause or constitute a material breach of any of its representations,
warranties or covenants contained herein.

                  6.11 Dividends. After the date of this Agreement, each of
Fifth Third and Old Kent shall coordinate with the other the declaration of any
dividends in respect of Fifth Third Common Stock and Old Kent Common Stock and
the record dates and payment dates relating thereto, it being the intention of
the parties hereto that holders of Old Kent Common Stock shall not receive two
dividends, or fail to receive one dividend, for any quarter with respect to
their shares of Old Kent Common Stock and any shares of Fifth Third Common Stock
any such holder receives in exchange therefor in the Merger (such holders to
receive four dividends during 2001).

                  6.12 Exemption from Liability Under Section 16(b). Assuming
that Old Kent delivers to Fifth Third the Section 16 Information (as defined
below) in a timely fashion, the Board of Directors of Fifth Third, or a
committee of Non-Employee Directors thereof (as such term is defined for
purposes of Rule 16b-3(d) under the Exchange Act), shall adopt a resolution
providing that the receipt by Old Kent Insiders of Fifth Third Common Stock in
exchange for shares of Old Kent Common Stock, and of options on Fifth Third
Common Stock upon conversion of options on Old Kent Common Stock, in each case
pursuant to the transactions contemplated hereby and to the extent such
securities are listed in the Section 16 Information, are intended to be exempt
from liability pursuant to Section 16(b) under the Exchange Act. "Section 16
Information" shall mean information accurate in all respects regarding Old Kent
Insiders, the number of shares of Old Kent Common Stock held by each such Old
Kent Insider and expected to be exchanged for Fifth Third Common Stock in the
Merger, and the number and description of the options on Old Kent Common Stock
held by each such Old Kent

                                       39
<PAGE>   47
Insider and expected to be converted into options on Fifth Third Common Stock in
connection with the Merger. The "Old Kent Insiders" shall mean those officers
and directors of Old Kent who are subject to the reporting requirements of
Section 16(a) of the Exchange Act and who are listed in the Section 16
Information.

                  6.13 Directorships. Fifth Third shall take such actions as may
be reasonably required to cause its Board of Directors to be expanded by three
members and to appoint three members of Old Kent's Board of Directors to the
Fifth Third Board of Directors. In addition, Fifth Third shall extend offers to
all individuals who are members of the Board of Directors of Old Kent
immediately prior to the Effective Time to become members of the Board of
Directors of Fifth Third's principal bank located in Michigan (or any successor
thereto) immediately after the Effective Time.

                  6.14 Aggregate Capitalization. Old Kent will not take any
action, or fail to take any action, that results in the aggregate number of
shares of Old Kent Common Stock outstanding immediately prior to the Effective
Time (including all shares of Old Kent Common Stock subject to Old Kent Rights
other than the Old Kent Option Agreement, but not including shares of Old Kent
Common Stock held in treasury) exceeding 150,000,000.

                  6.15 Community Commitments. From and after the Effective Time,
Fifth Third shall maintain the community commitments undertaken by Old Kent Bank
Subsidiaries prior to the date hereof and set forth in Section 6.15 of the Old
Kent Disclosure Schedule in the communities currently served by such banks.

                  6.16 Executive Benefit Trust. Notwithstanding anything to the
contrary, as soon as practicable after the execution of this Agreement, Old Kent
will take such actions as required under the terms of the Old Kent Executive
Severance Agreements and other executive non-qualified deferred compensation
plans, including, but not limited to, the funding of the Old Kent Financial
Corporation Executive Benefit Trust (a rabbi trust) as required in such
agreements, to the extent not already funded.

obtained by reason of the failure to obtain the required vote at the meetings of
the stockholders contemplated by Section 6.3, or at any adjournment or
postponement thereof at which a vote was taken;

                  (d) by either the Board of Directors of Fifth Third or the
Board of Directors of Old Kent if the Merger shall not have been consummated on
or before the first anniversary of the date hereof unless the failure of the
Closing to occur by such date shall be due to the failure of the party seeking
to terminate this Agreement to perform or observe the covenants and agreements
of such party set forth herein; or

                  (e) by either the Board of Directors of Fifth Third or the
Board of Directors of Old Kent (provided that the terminating party is not then
in breach of any representation, warranty, covenant or other agreement contained
herein) if there shall have been a breach of any of the covenants or agreements
or any of the representations or warranties set forth in this Agreement on the
part of Old Kent, in the case of a termination by Fifth Third, or Fifth Third,
in the case of a termination by Old Kent, which breach, either individually or
in the aggregate, would constitute, if occurring or continuing on the Closing
Date, the failure of the conditions set forth in Section 7.2 or 7.3, as the case
may be, and which is not cured within 45 days following written notice to the
party committing such breach or by its nature or timing cannot be cured prior to
the Closing Date.

                  8.2 Effect of Termination. In the event of termination of this
Agreement by either Fifth Third or Old Kent as provided in Section 8.1, this
Agreement shall forthwith become void and have no effect, and none of Fifth
Third, Old Kent, any of their respective Subsidiaries or any of the officers or
directors of any of them shall have any liability of any nature whatsoever
hereunder, or in connection with the transactions contemplated hereby, except
that (i) Sections 6.2(b), 8.2, 9.2 and 9.3 shall survive any termination of this
Agreement, and (ii) notwithstanding anything to the contrary contained in this
Agreement, neither Fifth Third nor Old Kent shall be relieved or released from
any liabilities or damages arising out of its willful breach of any provision of
this Agreement.

taken or authorized by their respective Boards of Directors, at any time before
or after approval of the matters presented in connection with the Merger by the
stockholders of Old Kent or Fifth Third, as the case may be. This Agreement may

agreement on the part of a party hereto to any such extension or waiver shall be

but such extension or waiver or failure to insist on strict compliance with an
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                       SECURITIES ACT OF 1933, AS AMENDED

                  STOCK OPTION AGREEMENT, dated as of November 20, 2000 (the
"Agreement"), by and between Old Kent Financial Corporation, a Michigan
corporation ("Issuer"), and Fifth Third Bancorp, an Ohio corporation
("Grantee").

                              W I T N E S S E T H:

                  WHEREAS, concurrently herewith Issuer and Grantee are entering
into an Agreement and Plan of Merger of even date herewith (the "Merger
Agreement"), providing for, among other things, the merger (the "Merger") of
Issuer with and into Grantee; and

                  WHEREAS, as a condition and inducement to Grantee's
willingness to enter into the Merger Agreement and in consideration therefor,
Issuer has agreed to grant Grantee the Option (as hereinafter defined);

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein and in the Merger Agreement, Issuer and Grantee agree as follows:

Section 1. Grant of Option; Adjustment. (a) Subject to the terms and conditions
set forth herein, Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase that number of fully paid and non-assessable
shares of common stock, par value $1.00 per share, of Issuer ("Common Stock")
equal to 19.9% of the currently issued and outstanding shares of Common Stock,
without giving effect to any shares subject to or issued pursuant to the Option,
at a purchase price of $25.00 per share (the "Option Price"). The number of
shares of Common Stock that may be received upon the exercise of the Option and
the Option Price are subject to adjustment as herein set forth.

                  (b) In the event that any additional shares of Common Stock
are either (i) issued or otherwise become outstanding after the date of this
Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased,
retired or otherwise cease to be outstanding after the date of this Agreement,
the number of shares of Common Stock subject to the Option shall be increased or
decreased, as appropriate, so that, after such issuance or redemption,
repurchase, retirement or other action, such number equals 19.9% of the number
of shares of Common Stock then issued and outstanding without giving effect to
any shares subject or issued pursuant to the Option. Nothing contained in this
Section 1(b) or elsewhere in this Agreement shall be deemed to authorize Issuer
or Grantee to breach any provision of the Merger Agreement.

                  Section 2. Exercise of Option. (a) The holder or holders of
the Option (the "Holder") may exercise the Option, in whole or in part, at any
time or from time to
<PAGE>   2
time, if, but only if, both an Initial Triggering Event (as hereinafter defined)
and a Subsequent Triggering Event (as hereinafter defined) shall have occurred
prior to the occurrence of an Exercise Termination Event (as hereinafter
defined); provided that the Holder shall have sent the written notice of such
exercise (as provided in subsection (e) of this Section 2) within 90 days
following such Subsequent Triggering Event. Each of the following shall be an
"Exercise Termination Event": (i) the Effective Time (as defined in the Merger
Agreement) of the Merger; (ii) termination of the Merger Agreement in accordance
with the provisions thereof, if such termination occurs prior to the occurrence
of an Initial Triggering Event, except a termination by Grantee pursuant to
Section 8.1(e) of the Merger Agreement (unless the breach by Issuer giving rise
to such right of termination is non-volitional); or (iii) the passage of 12
months after termination of the Merger Agreement, if such termination follows
the occurrence of an Initial Triggering Event or is a termination by Grantee
prior to the occurrence of an Initial Triggering Event pursuant to Section
8.1(e) of the Merger Agreement (unless the breach by Issuer giving rise to such
right of termination is non-volitional).

                  (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                           (i) Issuer or any of its subsidiaries (each an
         "Issuer Subsidiary"), without having received Grantee's prior written
         consent, shall have entered into an agreement to engage in an
         Acquisition Transaction (as hereinafter defined) with any person (the
         term "person" for purposes of this Agreement having the meaning
         assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities
         Exchange Act of 1934, as amended (the "1934 Act"), and the rules and
         regulations promulgated thereunder) other than Grantee or any of its
         subsidiaries (each a "Grantee Subsidiary"). For purposes of this
         Agreement, "Acquisition Transaction" shall mean (w) a merger or
         consolidation, or any similar transaction, involving Issuer or any
         Significant Subsidiary (as defined in Rule 1-02(w) of Regulation S-X
         promulgated by the Securities and Exchange Commission (the "SEC")) of
         Issuer, (x) a purchase, lease or other acquisition or assumption of all
         or a substantial portion of the assets or deposits of Issuer or any
         Significant Subsidiary of Issuer, (y) a purchase or other acquisition
         (including by way of merger, consolidation, share exchange or
         otherwise) of beneficial ownership (the term "beneficial ownership" for
         purposes of this Agreement having the meaning assigned thereto in
         Section 13(d) of the Exchange Act, and the rules and regulations
         thereunder) of securities representing 15% or more of the voting power
         of Issuer, or (z) any substantially similar transaction; provided,
         however, that in no event shall any merger, consolidation, purchase or
         similar transaction involving only the Issuer and one or more Issuer
         Subsidiaries or involving only any two or more Issuer Subsidiaries, be
         deemed to be an Acquisition Transaction; provided that any such
         transaction is not entered into in violation of the terms of the Merger
         Agreement;

                                       2
<PAGE>   3
                           (ii) (x) Issuer or any Significant Subsidiary of
         Issuer, or the Board of Directors of Issuer, without having received
         Grantee's prior written consent, shall have authorized, recommended to
         its stockholders, proposed or publicly announced its intention to
         authorize, recommend to its stockholders or propose, to engage in an
         Acquisition Transaction with any person other than Grantee or a Grantee
         Subsidiary, (y) the Board of Directors of Issuer shall have failed to
         make its recommendation that the Issuer stockholders approve the Merger
         Agreement and the transactions contemplated thereby in anticipation of
         engaging in an Acquisition Transaction or (z) the Board of Directors of
         Issuer shall have publicly withdrawn or modified, or publicly announced
         its intention to withdraw or modify, in any manner adverse to Grantee,
         its recommendation that the stockholders of Issuer approve the
         transactions contemplated by the Merger Agreement in anticipation of
         engaging in an Acquisition Transaction;

                           (iii) Any person other than Grantee, any Grantee
         Subsidiary or any Issuer Subsidiary acting in a fiduciary capacity in
         the ordinary course of its business shall have acquired beneficial
         ownership or the right to acquire beneficial ownership of 15% or more
         of the outstanding shares of Common Stock (the term "beneficial
         ownership" for purposes of this Agreement having the meaning assigned
         thereto in Section 13(d) of the 1934 Act, and the rules and regulations
         promulgated thereunder);

                           (iv) Any person other than Grantee or any Grantee
         Subsidiary shall have made a bona fide proposal to Issuer or its
         stockholders by public announcement or written communication that is or
         becomes the subject of public disclosure to engage in an Acquisition
         Transaction;

                           (v) After an overture is made by a third party to
         Issuer or its stockholders to engage in an Acquisition Transaction,
         Issuer shall have breached any covenant or obligation contained in the
         Merger Agreement (other than a non-volitional breach) and such breach
         (x) would entitle Grantee to terminate the Merger Agreement and (y)
         shall not have been cured prior to the Notice Date (as defined below);
         or

                           (vi) Any person other than Grantee or any Grantee
         Subsidiary, other than in connection with a transaction to which
         Grantee has given its prior written consent, shall have filed an
         application or notice with the Federal Reserve Board, or other federal
         or state bank regulatory authority, which application or notice has
         been accepted for processing, for approval to engage in an Acquisition
         Transaction.

                  (c) The term "Subsequent Triggering Event" shall mean either
of the following events or transactions occurring after the date hereof:

                                       3
<PAGE>   4
                           (i) The acquisition by any person (other than Grantee
         or any Grantee Subsidiary) of beneficial ownership of 25% or more of
         the then outstanding Common Stock; or

                           (ii) The occurrence of the Initial Triggering Event
         described in paragraph (i) of subsection (b) of this Section 2, except
         that the percentage referred to in clause (y) shall be 25%.

                  (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event of
which it has notice (together, a "Triggering Event"), it being understood that
the giving of such notice by Issuer shall not be a condition to the right of the
Holder to exercise the Option.

                  (e) In the event the Holder is entitled to and wishes to
exercise the Option, it shall send to Issuer a written notice (the date of which
being herein referred to as the "Notice Date") specifying (i) the total number
of shares it will purchase pursuant to such exercise and (ii) a place and date
not earlier than three business days nor later than 60 business days from the
Notice Date for the closing of such purchase (a "Closing"; and the date of such
Closing, a "Closing Date"); provided that if prior notification to or approval
of the Federal Reserve Board or any other regulatory agency is required in
connection with such purchase, the Holder shall promptly file the required
notice or application for approval and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification periods have expired or
been terminated, or such approvals have been obtained, and any requisite waiting
period or periods shall have passed. For purposes of determining the timeliness
of exercise, any exercise of the Option shall be deemed to occur on the Notice
Date relating thereto.

                  (f) At a Closing, the Holder shall pay to Issuer an amount
equal to the Option Price multiplied by the number of shares of Common Stock
purchased pursuant to the exercise of the Option in immediately available funds
by wire transfer to a bank account designated by Issuer, provided that failure
or refusal of Issuer to designate such a bank account shall not preclude the
Holder from exercising the Option.

                  (g) At such Closing, simultaneously with the delivery of
immediately available funds as provided in subsection (f) of this Section 2,
Issuer shall deliver to the Holder a certificate or certificates representing
the number of shares of Common Stock purchased by the Holder, which shares shall
be free and clear of all liens, charges or encumbrances, and, if the Option
should be exercised in part only, a new Option evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder, and
the Holder shall deliver to Issuer this Agreement and a letter agreeing that the
Holder will not offer to sell or otherwise dispose of such shares in violation
of applicable law or the provisions of this Agreement.

                  (h) Certificates for Common Stock delivered at a Closing
hereunder may be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject to certain provisions of an agreement between the
                  registered holder hereof and Issuer, dated as of November 20,
                  2000, and to resale restrictions arising under the Securities
                  Act of 1933, as amended. A copy of such agreement is on file
                  at the principal office of Issuer and will be provided to the
                  holder hereof without charge upon receipt by Issuer of a
                  written request therefor."

It is understood and agreed that:

                           (i) The reference to the resale restrictions of the
         Securities Act of 1933, as amended (the "1933 Act"), in the above
         legend shall be removed by delivery of substitute certificate(s)
         without such reference if the Holder shall have delivered to Issuer a
         copy of a letter from the staff of the SEC, or an opinion of counsel,
         in form and substance reasonably satisfactory to Issuer, to the effect
         that such legend is not required for purposes of the 1933 Act;

                           (ii) The reference to the provisions to this
         Agreement in the above legend shall be removed by delivery of
         substitute certificate(s) without such reference if the shares have
         been sold or transferred in compliance with the provisions of this
         Agreement and under circumstances that do not require the retention of
         such reference; and

                           (iii) The legend shall be removed in its entirety if
         the conditions in the preceding clauses (i) and (ii) are both
         satisfied. In addition, such certificates shall bear any other legend
         as may be required by law.

                  (i) Upon the giving by the Holder to Issuer of the written
notice of exercise of the Option provided for under subsection (e) of this
Section 2 and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder. Issuer shall pay all expenses, and any and all United States
federal, state and local taxes and other charges that may be payable in
connection with the preparation, issue and delivery of stock certificates under
this Section 2 in the name of the Holder or its assignee, transferee or
designee.

                  Section 3. Additional Covenants of Issuer. Issuer agrees: (a)
that it shall at all times maintain, free from preemptive rights, sufficient
authorized but unissued or

                                       5
<PAGE>   6
treasury shares of Common Stock so that the Option may be exercised without
additional authorization of Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to purchase Common
Stock; (b) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other voluntary
act, avoid or seek to avoid the observance or performance of any of the
covenants, stipulations or conditions to be observed or performed hereunder by
Issuer; (c) promptly to take all action as may from time to time be required
(including (i) complying with all premerger notification, reporting and waiting
period requirements specified in 15 U.S.C. Section 18a and the regulations
promulgated thereunder and (ii) in the event, under the Bank Holding Company Act
of 1956, as amended (the "BHCA"), or the Change in Bank Control Act of 1978, as
amended, or any state banking law, prior approval of or notice to the Federal
Reserve Board or to any state regulatory authority is necessary before the
Option may be exercised, cooperating fully with the Holder in preparing such
applications or notices and providing such information to the Federal Reserve
Board or such state regulatory authority as they may require) in order to permit
the Holder to exercise the Option and Issuer duly and effectively to issue
shares of Common Stock pursuant hereto; and (d) promptly to take all action
provided herein to protect the rights of the Holder against dilution.

                  Section 4. Exchange, Loss, Theft, etc. of Agreement. This
Agreement and the Option granted hereby are exchangeable, without expense, at
the option of the Holder, upon presentation and surrender of this Agreement at
the principal office of Issuer, for other Agreements providing for Options of
different denominations entitling the holder thereof to purchase, on the same
terms and subject to the same conditions as are set forth herein, in the
aggregate the same number of shares of Common Stock purchasable hereunder. The
terms "Agreement" and "Option" as used herein include any Stock Option
Agreements and related Options for which this Agreement (and the Option granted
hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

                  Section 5. Adjustments upon Changes in Capitalization, etc. In
addition to the adjustment in the number of shares of Common Stock that are
purchasable upon exercise of the Option pursuant to subsection (b) of Section 1
of this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5. In the event of any change in, or
distributions in respect of, the Common Stock by

                                       6
<PAGE>   7
reason of reclassifications, recapitalizations, stock dividends, stock splits,
split-ups, mergers, combinations, subdivisions, conversions, exchanges of
shares, dividends, dividends payable in other securities, distributions on or in
respect of the Common Stock, or the like, the type and number of shares of
Common Stock purchasable upon exercise hereof and the Option Price therefor
(including for purposes of repurchase thereof pursuant to Section 7) shall be
appropriately adjusted in such manner as shall fully preserve the economic
benefits provided hereunder and proper provision shall be made in any agreement
governing any such transaction to provide for such proper adjustment and the
full satisfaction of the Issuer's obligations hereunder.

                  Section 6. Registration Rights. Upon the occurrence of a
Subsequent Triggering Event that occurs prior to an Exercise Termination Event,
Issuer shall, at the request of Grantee delivered within 90 days of such
Subsequent Triggering Event (whether on its own behalf or on behalf of any
subsequent Holder of this Option, or part thereof, or any of the shares of
Common Stock issued pursuant hereto), promptly prepare, file and keep current a
shelf registration statement under the 1933 Act covering any shares issued and
issuable pursuant to this Option and shall use its reasonable best efforts to
cause such registration statement to become effective and remain current in
order to permit the sale or other disposition of this Option and any shares of
Common Stock issued upon total or partial exercise of this Option ("Option
Shares") in accordance with any plan of disposition requested by Grantee. Issuer
will use its reasonable best efforts to cause such registration statement first
to become effective and then to remain effective for such period not in excess
of 180 days from the day such registration statement first becomes effective or
such shorter time as may be reasonably necessary to effect such sales or other
dispositions. Grantee shall have the right to demand two such registrations. The
foregoing notwithstanding, if, at the time of any request by Grantee for
registration of the Option or Option Shares as provided above, Issuer is in
registration with respect to an underwritten public offering of shares of Common
Stock, and if, in the good faith judgment of the managing underwriter or
managing underwriters, or, if none, the sole underwriter or underwriters, of
such offering, the registration of the Holder's Option or Option Shares at such
time would interfere with the successful marketing of the shares of Common Stock
then being offered by Issuer, the number of Option Shares otherwise to be
covered in the registration statement contemplated hereby may be reduced;
provided, however, that after any such required reduction the number of Option
Shares to be registered for the account of the Holder shall constitute at least
25% of the total number of shares to be sold by the Holder and Issuer in the
aggregate; and provided further, however, that if such reduction occurs, then
the Issuer shall file a registration statement for the balance as promptly as
practicable and no reduction pursuant to this Section 6 shall thereafter occur.
Each Holder on behalf of which registration is requested shall provide all
information reasonably requested by Issuer for inclusion in any registration
statement to be filed hereunder. If requested by any such Holder in connection
with such registration, Issuer shall become a party to any underwriting
agreement relating to the

                                       7
<PAGE>   8
sale of such shares, but only to the extent of obligating itself in respect of
representations, warranties, indemnities and other agreements customarily
included in secondary offering underwriting agreements for the Issuer. Upon
receiving any request under this Section 6 from any Holder, Issuer agrees to
send a copy thereof to any other person known to Issuer to be entitled to
registration rights under this Section 6, in each case by promptly mailing the
same, postage prepaid, to the address of record of the persons entitled to
receive such copies. Notwithstanding anything to the contrary contained herein,
in no event shall Issuer be obligated to effect more than two registrations
pursuant to this Section 6 by reason of the fact that there shall be more than
one Grantee as a result of any assignment or division of this Agreement.

                  Section 7. Repurchase of Option. (a) From and after a
Repurchase Event (as defined below), (i) following a request of the Holder,
delivered prior to an Exercise Termination Event, Issuer (or any successor
thereto) shall repurchase the Option from the Holder at a price (the "Option
Repurchase Price") equal to the amount by which (x) the Market/Offer Price (as
defined below) exceeds (y) the Option Price, multiplied by the number of shares
for which this Option may then be exercised and (ii) at the request of the owner
of Option Shares from time to time (the "Owner"), delivered within 90 days of
such occurrence (or such later period as provided in Section 10), Issuer shall
repurchase such number of Option Shares from the Owner as the Owner shall
designate at a price (the "Option Share Repurchase Price") equal to the
Market/Offer Price multiplied by the number of Option Shares so designated,
provided, however, that the Option Purchase Price and Option Share Repurchase
Price shall be subject to the limitations set forth in Section 24. The term
"Market/Offer Price" shall mean the highest of (i) the price per share of Common
Stock at which a tender offer or exchange offer therefor has been made, (ii) the
price per share of Common Stock to be paid by any third party pursuant to an
agreement with Issuer, (iii) the highest closing price for shares of Common
Stock within the six-month period immediately preceding the date the Holder
gives notice of the required repurchase of this Option or the Owner gives notice
of the required repurchase of Option Shares, as the case may be, and (iv) in the
event of a sale of all or a substantial portion of Issuer's assets, the sum of
the price paid in such sale for such assets and the current market value of the
remaining assets of Issuer, less the current market value of the remaining
liabilities of Issuer, each such value as determined by a nationally recognized
investment banking firm selected by the Holder or the Owner, as the case may be,
and reasonably acceptable to the Issuer, divided by the number of shares of
Common Stock of Issuer outstanding at the time of such sale. In determining the
Market/Offer Price, the value of consideration other than cash shall be
determined by a nationally recognized investment banking firm selected by the
Holder or Owner, as the case may be, and reasonably acceptable to the Issuer.

                  (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office, this

                                       8
<PAGE>   9
Agreement or certificates for Option Shares, as applicable, accompanied by a
written notice or notices stating that the Holder or the Owner, as the case may
be, elects to require Issuer to repurchase this Option and/or the Option Shares
in accordance with the provisions of this Section 7. Such notice or notices
shall also contain representations and warranties to the effect that the Holder
owns the Option Shares to be repurchased, free and clear of all Liens, with full
power, right and authority to present such Option Shares for repurchase
hereunder. Within the latter to occur of (i) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (ii) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof, if any,
that Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation or as a consequence of administrative policy arising
thereunder from repurchasing the Option and/or the Option Shares in full, Issuer
shall immediately so notify the Holder and/or the Owner and thereafter deliver
or cause to be delivered, from time to time, the Holder and/or the Owner, as
appropriate, the portion of the Option Repurchase Price and the Option Share
Repurchase Price, respectively, that it is no longer prohibited from delivering,
within five business days after the date on which Issuer is no longer so
prohibited; provided, however, that if Issuer at any time after delivery of a
notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited
under applicable law or regulation or as a consequence of administrative policy
arising thereunder from repurchasing the Option or the Option Shares, as the
case may be, or from delivering to the Holder and/or the Owner, as appropriate,
the Option Repurchase Price and the Option Share Repurchase Price, respectively,
in full (and Issuer hereby undertakes to use its best efforts to obtain all
required regulatory and legal approvals and to file any required notices, in
each case as promptly as practicable in order to accomplish such repurchase),
the Holder or Owner may revoke its notice of repurchase of the Option or the
Option Shares either in whole or to the extent of the prohibition, whereupon, in
the latter case, Issuer shall promptly (i) deliver to the Holder and/or the
Owner, as appropriate, that portion of the Option Repurchase Price or the Option
Share Repurchase Price that Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (x) to the Holder, a new Stock Option Agreement
evidencing the right of the Holder to purchase that number of shares of Common
Stock obtained by multiplying the number of shares of Common Stock for which the
surrendered Stock Option Agreement was exercisable at the time of delivery of
the notice of repurchase by a fraction, the numerator of which is the Option
Repurchase Price less the portion thereof theretofore delivered to the Holder
and the denominator of which is the Option Repurchase Price, or (y) to the
Owner, a certificate for the Option Shares it is then so prohibited from
repurchasing.

                                       9
<PAGE>   10
                  (d) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of all or a substantial portion of the assets of Issuer, other
than any such transaction which would not constitute an Acquisition Transaction
pursuant to the provisos to Section 2(b)(i) hereof or (ii) upon the acquisition
by any person of beneficial ownership of 50% or more of the then outstanding
shares of Common Stock, provided that no such event described in clause (i) or
(ii) shall constitute a Repurchase Event unless a Subsequent Triggering Event
shall have occurred prior to an Exercise Termination Event. The parties hereto
agree that Issuer's obligations to repurchase the Option or Option Shares under
this Section 7 shall not terminate upon the occurrence of an Exercise
Termination Event, unless no Subsequent Triggering Event shall have occurred
prior to the occurrence of an Exercise Termination Event.

                  Section 8. Substitute Option. (a) In the event that prior to
an Exercise Termination Event, Issuer shall enter into an agreement (i) to
consolidate with or merge into any person, other than Grantee or a Grantee
Subsidiary, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or a
Grantee Subsidiary, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other person or cash or any other property or the then
outstanding shares of Common Stock shall after such merger represent less than
50% of the outstanding voting shares and voting share equivalents of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case, the agreement governing such transaction shall make proper
provision so that the Option shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, an option (the "Substitute Option"), at the election of
the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.

                  (b) The following terms have the meanings indicated:

                           (i) "Acquiring Corporation" shall mean (x) the
         continuing or surviving corporation of a consolidation or merger with
         Issuer (if other than Issuer), (y) Issuer in a merger in which Issuer
         is the continuing or surviving person, and (z) the transferee of all or
         substantially all of Issuer's assets.

                           (ii) "Substitute Common Stock" shall mean the common
         stock issued by the issuer of the Substitute Option upon exercise of
         the Substitute Option.

                                       10
<PAGE>   11
                           (iii) "Assigned Value" shall mean the Market/Offer
         Price, as defined in Section 7.

                           (iv) "Average Price" shall mean the average closing
         price of a share of the Substitute Common Stock for the one year
         immediately preceding the consolidation, merger or sale in question,
         but in no event higher than the closing price of the shares of
         Substitute Common Stock on the day preceding such consolidation, merger
         or sale; provided that if Issuer is the issuer of the Substitute
         Option, the Average Price shall be computed with respect to a share of
         common stock issued by the person merging into Issuer or by any company
         which controls or is controlled by such person, as the Holder may
         elect.

                  (c) The Substitute Option shall have the same terms as the
Option, provided that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Option shall also enter into an agreement with the then holder or holders of the
Substitute Option (the "Substitute Option Holder") in substantially the same
form as this Agreement, which shall be applicable to the Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock as is equal to the Assigned Value
multiplied by the number of shares of Common Stock for which the Option is then
exercisable, divided by the Average Price. The exercise price of the Substitute
Option per share of Substitute Common Stock shall then be equal to the Option
Price multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock for which the Option is then exercisable and the
denominator of which shall be the number of shares of Substitute Common Stock
for which the Substitute Option is exercisable.

                  (e) In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than 19.9%
of the shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "Substitute Option
Issuer") shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Acquiring
Corporation.

                  (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

<PAGE>   12
                  Section 9. Repurchase of Substitute Option. (a) At the request
of the Substitute Option Holder, the Substitute Option Issuer shall repurchase
the Substitute Option from the Substitute Option Holder at a price (the
"Substitute Option Repurchase Price") equal to the amount by which (i) the
Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price
of the Substitute Option, multiplied by the number of shares of Substitute
Common Stock for which the Substitute Option may then be exercised, and at the
request of the owner (the "Substitute Share Owner") of shares of Substitute
Common Stock (the "Substitute Shares"), the Substitute Option Issuer shall
repurchase the Substitute Shares at a price (the "Substitute Share Repurchase
Price") equal to the Highest Closing Price multiplied by the number of
Substitute Shares so designated. The term "Highest Closing Price" shall mean the
highest closing price for shares of Substitute Common Stock within the six-month
period immediately preceding the date the Substitute Option Holder gives notice
of the required repurchase of the Substitute Option or the Substitute Share
Owner gives notice of the required repurchase of the Substitute Shares, as
applicable.

                  (b) The Substitute Option Holder and the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, a copy of this
Agreement) and certificates for Substitute Shares accompanied by a written
notice or notices stating that the Substitute Option Holder or the Substitute
Share Owner, as the case may be, elects to require the Substitute Option Issuer
to repurchase the Substitute Option and/or the Substitute Shares in accordance
with the provisions of this Section 9. As promptly as practicable, and in any
event within five business days after the surrender of the Substitute Option
and/or certificates representing Substitute Shares and the receipt of such
notice or notices relating thereto, the Substitute Option Issuer shall deliver
or cause to be delivered to the Substitute Option Holder the Substitute Option
Repurchase Price and/or to the Substitute Share Owner the Substitute Share
Repurchase Price therefor or, in either case, the portion thereof which the
Substitute Option Issuer is not then prohibited under applicable law and
regulation or as a consequence of administrative policy arising thereunder from
so delivering.

                  (c) To the extent the Substitute Option Issuer is prohibited
under applicable law or regulation or as a consequence of administrative policy
arising thereunder from repurchasing the Substitute Option and/or the Substitute
Shares in part or in full, the Substitute Option Issuer following a request for
repurchase pursuant to this Section 9 shall immediately so notify the Substitute
Option Holder and/or the Substitute Share Owner and thereafter deliver or cause
to be delivered, from time to time, to the Substitute Option Holder and/or the
Substitute Share Owner, as appropriate, the portion of the Substitute Share
Repurchase Price, respectively, which it is no longer prohibited from
delivering, within five business days after the date on which

                                       12
<PAGE>   13
the Substitute Option Issuer is no longer so prohibited; provided, however, that
if the Substitute Option Issuer is at any time after delivery of a notice of
repurchase pursuant to subsection (b) of this Section 9 prohibited under
applicable law or regulation or as a consequence of administrative policy
arising thereunder from delivering to the Substitute Option Holder and/or the
Substitute Share Owner, as appropriate, the Substitute Option Repurchase Price
and the Substitute Share Repurchase Price, respectively, in full (and the
Substitute Option Issuer shall use its best efforts to obtain all required
regulatory and legal approvals, in each case as promptly as practicable, in
order to accomplish such repurchase), the Substitute Option Holder or Substitute
Share Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, the Substitute Option Issuer shall promptly (i)
deliver to the Substitute Option Holder or Substitute Share Owner, as
appropriate, that portion of the Substitute Option Repurchase Price or the
Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (x) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, or (y) to the Substitute Share
Owner, a certificate for the Substitute Common Shares it is then so prohibited
from repurchasing.

                  Section 10. Extension of Exercise Period. The 90-day period
for exercise of certain rights under Sections 2, 6, 7 and 13 shall be extended:
(a) to the extent necessary to obtain all regulatory approvals for the exercise
of such rights and for the expiration of all statutory waiting periods; and (b)
to the extent necessary to avoid liability under Section 16(b) of the 1934 Act
by reason of such exercise.

                  Section 11. Representations and Warranties of Issuer. Issuer
hereby represents and warrants to Grantee as follows:

                  (a) Issuer has all requisite corporate power and authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the

validly executed and delivered by Issuer.

                                       13
<PAGE>   14
termination of this Agreement in accordance with its terms will have reserved

Stock equal to the maximum number of shares of Common Stock at any time and from
time to time issuable hereunder, and all such shares, upon issuance pursuant
hereto, will be duly authorized, validly issued, fully paid, non-assessable, and
will be delivered free and clear of all claims, liens, encumbrance and security
interests and not subject to any preemptive rights.

                  (c) Issuer has taken all action (including, if required,
amending or terminating the Rights Agreement dated as of January 20, 1997, as
amended, between Issuer and Old Kent Bank, as rights agent, or redeeming all of
the rights ("Rights") under such Rights Agreement) so that the entering into
this Agreement, the acquisition of shares of Common Stock hereunder and the
other transactions contemplated hereby do not and will not result in the grant
of any rights to any person under the Rights Agreement or enable or require the
Rights to be exercised, distributed or triggered.

                  Section 12. Representations and Warranties of Grantee. Grantee
hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
enter into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee. This Agreement has been duly and validly executed and delivered by
Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the 1933 Act.

                  Section 13. Assignment. Neither of the parties hereto may
assign any of its rights or obligations under this Agreement or the Option
created hereunder to any other person, without the express written consent of
the other party, except that in the event a Subsequent Triggering Event shall
have occurred prior to an Exercise Termination Event, Grantee, subject to the
express provisions hereof, may assign in whole or in part its rights and
obligations hereunder within 90 days following such Subsequent Triggering Event
(or such later period as provided in Section 10); provided, however, that until
the date 15 days following the date on which the Federal Reserve Board approves
an application by Grantee under the BHCA to acquire the shares of Common Stock
subject to the Option, Grantee may not assign its rights under the Option,
except in (a) a widely dispersed public distribution, (b) a private placement in
which no one party acquires the right to purchase in excess of 2% of the voting
shares of Issuer, (c) an assignment to a single party (e.g., a broker or
investment banker) for the

                                       14
<PAGE>   15
purpose of conducting a widely dispersed public distribution on Grantee's behalf
or (d) any other manner approved by the Federal Reserve Board.

                  Section 14. Further Assurances. Each of Grantee and Issuer
will use its reasonable best efforts to make all filings with, and to obtain
consents of, all third parties and governmental authorities necessary to the
consummation of the transactions contemplated by this Agreement, including
without limitation making application to list the shares of Common Stock
issuable hereunder on the New York Stock Exchange upon official notice of
issuance and applying to the Federal Reserve Board under the BHCA for approval
to acquire the shares issuable hereunder, but Grantee shall not be obligated to
apply to state banking authorities for approval to acquire the shares of Common
Stock issuable hereunder until such time, if ever, as it deems appropriate to do
so.

                  Section 15. Surrender. (a) Grantee may, at any time during
which Issuer would be required to repurchase the Option or any Option Shares
pursuant to Section 7, surrender the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal
to the Surrender Price (as defined below); provided, however, that Grantee may
not exercise its rights pursuant to this Section 15 if Issuer has repurchased
the Option (or any portion thereof) or any Option Shares pursuant to Section 7.
The "Surrender Price" shall be equal to (i) $150 million, plus (ii) if
applicable, the aggregate purchase price previously paid pursuant hereto by
Grantee with respect to any Option Shares, minus (iii) if applicable, the sum of
(x) the excess of (1) the net cash amounts, if any, received by Grantee pursuant
to the arms' length sale of Option Shares (or any other securities into which
such Option Shares were converted or exchanged) to any party not affiliated with
Grantee, over (2) the aggregate purchase price previously paid pursuant hereto
by Grantee with respect to such Option Shares and (y) the net cash amounts, if
any, received by Grantee pursuant to an arms' length sale of a portion of the
Option to any party not affiliated with Grantee.

                  (b) Grantee may exercise its right to surrender the Option and
any Option Shares pursuant to this Section 15 by surrendering to Issuer, at its
principal office, this Agreement together with certificates for Option Shares,
if any, accompanied by a written notice stating (i) that Grantee elects to
surrender the Option and Option Shares, if any, in accordance with the
provisions of this Section 15 and (ii) the Surrender Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation or as a consequence of administrative policy arising
thereunder from paying the Surrender Price to Grantee in full, Issuer shall
immediately so notify Grantee and thereafter deliver or cause to be delivered,
from time to time, to Grantee, the portion of the Surrender Price that Issuer is
no longer prohibited from paying, within five business

                                       15
<PAGE>   16
days after the date on which Issuer is no longer so prohibited, provided,
however, that if Issuer at any time after delivery of a notice of surrender
pursuant to paragraph (b) of this Section 15 is prohibited under applicable law
or regulation or as a consequence of administrative policy arising thereunder
from paying to Grantee the Surrender Price in full (i) Issuer shall (x) use its
reasonable best efforts to obtain all required regulatory and legal approvals
and to file any required notices as promptly as practicable in order to make
such payments, (y) within five days of the submission or receipt of any
documents relating to any such regulatory and legal approvals, provide Grantee
with copies of the same, and (z) keep Grantee advised of both the status of any
such request for regulatory and legal approvals, as well as any discussions with
any relevant regulatory or other third party reasonably related to the same and
(ii) Grantee may revoke such notice of surrender by delivery of a notice of
revocation to Issuer and, upon delivery of such notice of revocation, the
Exercise Termination Date shall be extended to a date six months from the date
on which the Exercise Termination Date would have occurred if not for the
provisions of subsection (c) of this Section 15 (during which period Grantee may
exercise any of its rights hereunder, including any and all rights pursuant to
this Section 15).

                  (d) Grantee shall have rights substantially identical to those
set forth in subsections (a), (b) and (c) of this Section 15 with respect to the
Substitute Option and the Substitute Option Issuer during any period in which
the Substitute Option Issuer would be required to repurchase the Substitute
Option pursuant to Section 9.

                  Section 16. Equitable Relief. The parties hereto acknowledge
that damages would be an inadequate remedy for a breach of this Agreement by
either party hereto and that the obligations of the parties hereto shall be
enforceable by either party hereto through injunctive or other equitable relief.

                  Section 17. Severability. If any term, provision, covenant or
restriction contained in this Agreement is held by a court or a federal or state
regulatory agency of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions and covenants and
restrictions contained in this Agreement shall remain in full force and effect,
and shall in no way be affected, impaired or invalidated. If for any reason such
court or regulatory agency determines that the Holder is not permitted to
acquire, or Issuer is not permitted to repurchase pursuant to Section 7, the
full number of shares of Common Stock provided in Section 1(a) hereof (as
adjusted pursuant to Section 1(b) or 5 hereof), it is the express intention of
Issuer to allow the Holder to acquire or to require Issuer to repurchase such
lesser number of shares as may be permissible, without any amendment or
modification hereof.

                  Section 18. Delivery. All notices, requests, claims, demands
and other communications hereunder shall be deemed to have been duly given when
delivered in person, by cable, telegram, telecopy or telex, or by registered or
certified mail (postage

                                       16
<PAGE>   17
prepaid, return receipt requested) at the respective addresses of the parties
set forth in the Merger Agreement.

                  Section 19. Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, regardless
of the laws that might otherwise govern under applicable principles of conflicts
of laws thereof (except to the extent that mandatory provisions of federal or
state law apply).

                  Section 20. Counterparts. This Agreement may be executed in
two counterparts, each of which shall be deemed to be an original, but all of
which shall constitute one and the same agreement.

                  Section 21. Expenses. Except as otherwise expressly provided
herein, each of the parties hereto shall bear and pay all costs and expenses
incurred by it or on its behalf in connection with the transactions contemplated
hereunder, including fees and expenses of its own financial consultants,
investment bankers, accountants and counsel.

                  Section 22. Entire Agreement; No Third Party Beneficiaries.
Except as otherwise expressly provided herein or in the Merger Agreement, this
Agreement contains the entire agreement between the parties with respect to the
transactions contemplated hereunder and supersedes all prior arrangements or
understandings with respect thereto, written or oral. The terms and conditions
of this Agreement shall inure to the benefit of and be binding upon the parties
hereto and their respective successors and permitted assigns. Nothing in this
Agreement, expressed or implied, is intended to confer upon any party, other
than the parties hereto, and their respective successors and permitted assigns,
any rights, remedies, obligations or liabilities under or by reason of this
Agreement, except as expressly provided herein.

                  Section 23. Capitalized Terms. Capitalized terms used in this
Agreement and not defined herein shall have the meanings assigned thereto in the
Merger Agreement.

                  Section 24. Limitation on Grantee's Total Profit. (a)
Notwithstanding any other provision herein, in no event shall Grantee's Total
Profit (as defined in subsection (c) of this Section 24) exceed $200 million
(the "Maximum Profit"), and, if the Total Profit would otherwise exceed such
amount, Grantee, at its sole election, shall either (i) reduce the number of
shares subject to the Option (and any Substitute Option), (ii) deliver to
Issuer, or Substitute Issuer, as the case may be, for cancellation shares of
Common Stock or Substitute Common Stock, as the case may be, previously
purchased by Grantee valued at fair market value at the time of delivery, (iii)
pay cash to Issuer, or Substitute Issuer, as the case may be, (iv) reduce the
amount of the Section 7 Option Repurchase Price or Section 9 Substitute Option
Repurchase Price, or (v) undertake any combination of the foregoing, so that
Grantee's actually realized Total

                                       17
<PAGE>   18
Profit shall not exceed the Maximum Profit after taking into account the
foregoing actions.

                  (b) Notwithstanding any other provision of this Agreement, the
Option may not be exercised for a number of shares as would, as of the date of
exercise, result in a Notional Total Profit (as defined in subsection (d) of
this Section 24) of more than the Maximum Profit and, if exercise of the Option
would otherwise result in the Notional Total Profit exceeding such amount,
Grantee, in its discretion, may take any of the actions specified in subsection
(a) of this Section 24 so that the Notional Total Profit shall not restrict any
subsequent exercise of the Option which at such time complies with this
sentence.

                  (c) For purposes of this Agreement, the term "Total Profit"
shall mean the aggregate amount (before taxes) of the following: (i) the excess
of (x) the net cash amounts or fair market value of any property received by
Grantee pursuant to the sale of the Option or the Option Shares (or any other
securities into which such Option Shares are converted or exchanged) to any
unaffiliated party, other than any amount received by Grantee upon the
repurchase of the Option or the Option Shares, respectively, by Issuer pursuant
to Section 7 hereof, after payment of application brokerage or sales commissions
and discounts, over (y) Grantee's aggregate purchase price for such Option
Shares (or other securities), plus (ii) all amounts received by Grantee upon the
repurchase of the Option or the Option Shares by Issuer pursuant to Section 7
hereof, plus (iii) all equivalent amounts with respect to the Substitute Option
and Substitute Shares and any amounts paid pursuant to Section 9 hereof.

                  (d) For purposes of this Agreement, the term "Notional Total
Profit" with respect to any number of shares as to which Grantee may propose to
exercise the Option shall be the Total Profit, determined as of the date of such
proposed exercise assuming that the Option were exercised on such date for such
number of shares, and assuming that such shares, together with all other Option
Shares held by Grantee and its affiliates as of such date, were sold for cash at
the closing market price for the Common Stock as of the close of business on the
preceding trading day (less customary brokerage commissions). For purposes of
this Section 24, transactions by a wholly-owned subsidiary transferee of Grantee
in respect of the Option Shares transferred to it shall be treated as if made by
Grantee.

FIFTH THIRD & OLD KENT TO MERGE

o EXPANDS FIFTH THIRD'S PRESENCE TO 3RD IN MICHIGAN AND 5TH IN CHICAGO

o IMMEDIATELY ACCRETIVE TO EPS, BEFORE COST SAVINGS AND REVENUE ENHANCEMENT
  OPPORTUNITIES

o MAINTAINS HISTORICALLY SUPERIOR FIFTH THIRD OPERATING RATIOS,
  BALANCE SHEET STRENGTH

o PROVIDES SUBSTANTIAL REVENUE EXPANSION POTENTIAL WITH OLD KENT'S ONE MILLION
  CUSTOMERS

o LOW-RISK INTEGRATION

         FIFTH THIRD BANCORP (NASDAQ: FITB) and OLD KENT (NYSE: OK) announced
today the signing of a definitive agreement in which Fifth Third will merge with
Old Kent, headquartered in Grand Rapids, Michigan. Old Kent is a financial
holding company with a 41-year history of consecutive annual increases in
earnings per share and dividends. With assets of $22.5 billion, it operates over
300 banking offices in Michigan, Illinois and Indiana, as well as Old Kent
Mortgage Company.

         Fifth Third continues its profitable growth in the Midwest. The
combined company will have $69.1 billion in assets, $43.8 billion in deposits
and over 980 banking locations, primarily in Ohio, Kentucky, Indiana, Michigan
and Illinois. Fifth Third will be the second largest banking franchise, based on
deposits, in these attractive Midwestern states.

         Fifth Third President & CEO George A. Schaefer, Jr. states, "We
strongly believe that we have seized a unique opportunity to merge with one of
the strongest, highest quality franchises in the Midwest. David Wagner and his
management team have built a strong franchise that we've long admired, and one
with which we are confident we can grow revenues in historical Fifth Third
fashion."

         Schaefer continues, "Old Kent's financial strength, stable credit
quality and concentration in attractive Midwestern cities provides the best
platform for us to proceed with our Michigan and Chicago expansion strategies.
Having successfully completed the integration of CNB Bancshares earlier this
year, in August we announced our intent to acquire Ottawa Financial Corporation
in Holland, Michigan. The Old Kent and Ottawa transactions are consistent with
our steady growth pattern and position us for continued growth and service to
Chicago and Michigan-area customers."

         Fifth Third will exchange, on a tax-free basis, 0.74 shares of its
common stock for each share of Old Kent common stock. Based on Fifth Third's
November 17, 2000 closing price of $48.06, the transaction is valued at
approximately $4.9 billion. The transaction is expected to be approximately 11
percent accretive to Fifth Third's 2001 earnings per share (based on IBES
estimates). In addition, the transaction will significantly exceed Fifth Third's
internal rate of return goals. Management of the combined company expects to
achieve cost savings of 20 percent of Old Kent's total operating expenses, with
these savings being phased in 25 percent in 2001, 75 percent in 2002 and 100
percent by 2003. Fifth Third expects to incur merger-related charges of
approximately $235 million, after tax. The transaction is expected to be
completed in the second quarter of 2001 and accounted for as a pooling of
interests.

         Old Kent Chairman, President & CEO David Wagner remarked, "We are
extremely excited about this opportunity to team up with Fifth Third for a
number of reasons. In Fifth Third, with its outstanding performance record, we
have found a partner with whom we can continue to deliver upon our commitment to
create long-term shareholder value. A great deal of time and money has been
spent to build the franchise we have today, and this merger provides us with the
opportunity to continue to build upon the success of the past."

         "Merging with Fifth Third gives us the competitive edge we need to
continue to serve the financial needs of both individuals and businesses. Their
size, stability and overall market presence will enhance the types of products
we offer and significantly expand our presence throughout our primary five state
operating region. Old Kent and Fifth Third are two of the most consistently
profitable and growing banks in the Midwest, and we're excited to create such a
strong banking franchise in the attractive growth markets of Michigan and
Illinois."

         Wagner continued, "In addition, we believe that Fifth Third's operating
philosophy will benefit our employees, our customers and the communities in
which we operate. Employees and customers alike will be well served by Fifth
Third's long-standing practice of operating with local decision-makers, local
employees and a local Board of Directors."

         "Both Old Kent and Fifth Third firmly believe that building stronger
communities builds stronger banks. We have a long history of community
development in our markets, and so does Fifth Third. BLITZ, Fifth Third's
community development program, is funding $9 billion in Building, Lending,
Investments and Technology Zones initiatives throughout our seven-state region,
and we are committed to furthering this aggressive pledge."

         Continuing its commitment to growth through strong decentralized
management, Fifth Third will establish Fifth Third Bank, Michigan with three
main banks in Grand Rapids, Detroit and Traverse City. David J. Wagner will
serve as Chairman & CEO of Fifth Third Bank, Michigan and remain in Grand
Rapids. He will become one of three new directors added to Fifth Third Bancorp's
Board of Directors as a result of this transaction. Kevin T. Kabat of Old Kent
will be President, Fifth Third Bank in Grand Rapids; Bradlee F. Stamper,
currently Fifth Third President & CEO in Northern Indiana, will lead Fifth Third
Bank, Chicago; and Robert H. Warrington will serve as President of the Fifth
Third Mortgage Company.

         Following the merger, Fifth Third will continue to be one of the
nation's most solid, highest performing financial institutions, with a
diversified source of income. On a pro forma basis, net income sources will
consist of: retail/community banking, 44 percent; corporate banking, 29 percent;
investment/insurance, 9 percent; data processing, 7 percent; and mortgage
banking, 5 percent. On a pro forma basis for the twelve months ended September
30, 2000, including the effect of anticipated cost savings, the combined company
had return on assets of 1.93 percent; return on average equity of 21.8 percent;
and an efficiency ratio of 42.9 percent.

         Due diligence on the transaction has been completed by both parties and
completion of the transaction is subject to normal regulatory approvals and
approval of Fifth Third and Old Kent shareholders. Old Kent has granted Fifth
Third an option to purchase 19.9 percent of its common shares under certain
circumstances.

         Fifth Third was advised in this transaction by the investment bank of
Salomon Smith Barney Inc. and the law firm of Cleary, Gottlieb, Steen &
Hamilton. Old Kent was advised by the investment bank of Merrill Lynch and the
law firm of Wachtell, Lipton, Rosen & Katz.
